March 24, 2015

Somerset, New Jersey (USA) – NEI Corporation announced today that it has introduced NANOMYTE® MEND-RT, a self-healing, polymer nanocomposite coating for use as an intermediate layer in coating systems on metal substrates. When the coating system is physically damaged, the self-healing intermediate layer repairs the damage autonomously at near ambient conditions, closing and sealing the gap and protecting the metal from exposure to the elements. This new feature of physical gap closing provides an alternative to chemical self-healing observed in chromate coatings. The universal nature of this new technology makes it applicable in any chromate-free coating system where self-healing is desired. This unique feature can lead to preserving the aesthetics of a coated surface or providing active corrosion protection on metal surfaces, without changing the formulation of the conventional coating. The intermediate layer can be easily applied by dip, spray, brush or drawdown methods.

The MEND-RT layer is introduced in a traditional coating system without deteriorating the original properties of the coating stack. The technology is applicable to coatings on both ferrous and non-ferrous metals and alloys, such as magnesium, aluminum, copper, zinc and alloys thereof, and steel. The efficacy of the NANOMYTE® MEND-RT coating was confirmed on aluminum alloys, which are used extensively in the aerospace industry. Two sets of coating systems were applied and compared for corrosion resistance. The first coating stack consisted of a chromate-free corrosion resistant pretreatment, a chromate-free epoxy primer, and a standard polyurethane topcoat. The second stack was identical to the first one, with the additional MEND-RT layer inserted between the primer and topcoat. Corrosion resistance was evaluated using the Salt Spray Test (SST) ASTM B-117 method. Artificial defects were made on the coated panels before exposing them to salt spray. The first set of panels, i.e. without the self-healing inter-layer, exhibited early signs of corrosion with white corrosion buildup in the scribed region. The samples with MEND-RT showed enhanced protection with no signs of corrosion after 1,250 hours of exposure.

NANOMYTE® MEND-RT is available as a two-part product. Given that different applications utilize a variety of coating systems, NEI can undertake an in-house study to evaluate the efficacy of MEND-RT in the specific coating system used by the customer. If needed, the MEND-RT formulation can be customized to suit the requirements of the application. Alternatively, customers also have the option of purchasing MEND-RT and applying the coating at their facilities or through their vendors.

A New Approach To Using Self-healing Coatings

Utilizing a Self-Healing Coating to Impart Enhanced Corrosion Protection to Metals

A traditional protective coating system on a metal substrate generally consists of a pretreatment, primer, and a topcoat. The base metal is pretreated and primed for enhanced adhesion and corrosion resistance. A topcoat is then applied on the primer. Many of the coatings in use today to inhibit corrosion are “passive” in nature, in that they provide only barrier protection and/or promote adhesion between the metal and overlaying paint. While these are important attributes, passive solutions do not offer the same level of protection as coatings that provide “active” corrosion protection. To date, coatings that repair themselves when damaged are limited to either unconventional chemistries or uncommonly used polymers, which require forming a complex molecular network and are too soft to satisfy the mechanical robustness required in a protective topcoat.

An “active” corrosion protection coating, or self-healing coating, can be categorized into two classes according to their self-healing mechanisms: chemical or physical. The traditional chromate-based corrosion protection coating uses hexavalent chromium either in the pretreatment or the primer, or both, to achieve chemical self-healing. In contrast, NEI’s self-healing coating involves physical gap closing and crack sealing, which has the potential to impart performance that matches that of a chromate-based system. Figure 1 illustrates the coating architecture containing NANOMYTE® MEND-RT, a self-healing intermediate layer between the topcoat and the primer. When the coating is physically damaged, the self-healing intermediate layer physically repairs the damage autonomously, closing and sealing the gap and providing an active physical barrier.

Self-Healing Coating System Architecture – (a) A defect occurs in the coating system; (b) The self-healing coating, MEND-RT, closes the defect and prevents further crack propagation.

Self-Healing Coating System Architecture – (a) A defect occurs in the coating system; (b) The self-healing coating, MEND-RT, closes the defect and prevents further crack propagation.

An obvious advantage with the use of a self-healing intermediate layer as shown in Figure 1 is that the topcoat is a standard topcoat, which satisfies all industrial standards. The main function of NANOMYTE® MEND-RT, the intermediate self-healing layer, is to self-repair damages. By separating the topcoat functions and the self-healing function into two distinct layers, a self-healing capability is added to the conventional coating system. The composition of MEND-RT is such that the adhesion between the primer and the topcoat is preserved. The MEND-RT layer can be introduced in any coating system, without deteriorating the original properties of the coating stack. MEND-RT can be used with any coating system applied on ferrous or non-ferrous metals, such as magnesium, aluminum, copper, zinc and alloys thereof, and steel.

The efficacy of the self-healing intermediate layer, MEND-RT, was verified using the standard accelerated test method. A chromate-free, self-healing coating system was applied on aluminum 2024 and 7075 alloys. Aluminum was selected for this evaluation as it is extensively used with chromate coatings in the aerospace and aircraft industry due to its high strength and light weight. Two sets of coating systems were applied and compared for corrosion resistance. The first coating stack consisted of a chromate-free corrosion resistant pretreatment, a chromate-free epoxy primer, and a standard polyurethane topcoat. The second stack was identical to the first one, but had MEND-RT inserted between the primer and topcoat. Corrosion resistance was evaluated using the Salt Spray Test (SST) ASTM B-117 method. Artificial defects (“X” shaped scribes) were made on the coated panels before exposing them to salt spray. The photographs in Figure 2 show the progression of corrosion on Al 2024 and 7075 coupons after 1,250 hours of SST.

Photographs showing trends in corrosion resistance for Al 2024 and 7075 4” x 6” panels after 1,250 hours in salt spray test – (a) Commercial non-chromate coating system; (b) Commercial non-Chromate coating system with NANOMYTE® MEND-RT.

The first set of panels, i.e. without the self-healing interlayer, exhibited early signs of corrosion with white corrosion buildup in the scribed region. The samples with MEND-RT showed enhanced protection with no signs of corrosion. Examination under the microscope revealed that the defects in the coating were physically sealed by the MEND-RT coating. In addition, the gap closing occurred at near ambient temperature, without any external heat or other stimuli. This is direct evidence that the introduction of MEND-RT enhances the corrosion resistance of a coating system, leading to a longer lifetime of the coating.

NEI introduces NANOMYTE® SuperAi, a Durable Anti-ice Coating

« Recent NEI News
View / Download in PDF »

December 3, 2014

Somerset, New Jersey (USA): NEI Corporation announced today that it has introduced NANOMYTE® SuperAi – a nanocomposite coating that imparts anti-icing properties to the underlying substrate. The transparent coating also provides a hard, dense and smooth finish. Surfaces treated with SuperAi exhibit reduced ice adhesion, thereby preventing ice buildup. SuperAi can be applied to a variety of substrates, including plastics, metals, glass, and ceramics. In some instances, a suitable primer may be required for maximum adhesion of the anti-ice coating.

NANOMYTE® SuperAi is a single component coating that is easily applied by dip, spray, or brush. Potential applications include occurrences where ice removal is a challenge (e.g., wind turbine blades, power transmission lines and cables, windshields and other glass surfaces in automobiles). The coating also provides durability and additional corrosion protection. The figure below is an example of how SuperAi can eliminate ice buildup on a substrate.

SuperAi

SuperAi is uniquely engineered so that the treated surface becomes highly slippery and hydrophobic, which facilitates the reduction in ice adhesion. Data obtained so far by our customers and collaborators indicate that SuperAi is effective in mitigating buildup under icing conditions. For example, in a simulated industrial trial, ice accretion on coated and uncoated aluminum conductor cables were measured. The outside of one cable was coated with SuperAi. Both coated and uncoated conductors were subjected to icing conditions for two hours under a regulated spray of water and ice solution at fixed time intervals. Ice accumulation was determined by weighing the cables before and after the test. It was established, in multiple test runs, that the ice accretion was reduced to half with application of the coating. Similar results were obtained on sections of a wind turbine. In addition, in-house measurements of ice adhesion strength with a force gauge show that SuperAi reduces the adhesion tendency significantly.

NANOMYTE® SuperAi can be applied on clean surfaces using a commercial high volume, low pressure (HVLP) spray gun. The coating can also be applied using a roller or brush, where coating is done in a cross-pattern; left to right, then up and down as quickly as possible since the coating dries quickly. SuperAi can be cured at room temperature by exposing the coating to ambient conditions for 6 to 8 hours. Accelerated curing is achieved in 1 hour or less at temperatures in the range of 100 – 150°C. NANOMYTE® SuperAi is available in one liter bottles, 5 gallon pails, and 55 gallon drums.

NEI Development Update on NANOMYTE® TC-5001, a Protective Coating for Zinc-Plated and Galvanized Steel

« Recent NEI News
View / Download in PDF »

November 5, 2014

Somerset, New Jersey (USA): NEI Corporation has issued a product update, following the successful introduction of NANOMYTE® TC‐5001 – a nanotechnology-enabled, anti-corrosion coating for zinc‐plated and hot‐dip galvanized (HDG) steel. TC-5001 is a nanostructured composite coating consisting of organic and inorganic phases. It can be used either as a standalone coating or with the water-based, self-healing pretreatment, NANOMYTE® PT-100. In its current form, TC-5001 can be applied on metallic parts that have a zinc-based finish. Recent developments on its effectiveness and usage are outlined below.

Field Trials

Over the past couple of years, TC-5001 and related products have found use in several applications in different industries. Examples include:

Automotive Components and Support Structures

Automotive parts coated in-house were subjected to salt-spray testing (ASTM B117) for over 1,000 hours to test the effects of corrosion; the TC-5001-coated parts showed no signs of white rust. Additionally, parts plated with alloys of zinc and aluminum were also coated with TC-5001 and are currently undergoing field testing.

Examples of structural parts that can be coated with TC-5001 (or related products) for corrosion protection are shown on the right.

Automotive_Components

Outdoor Structures

Strain Insulators

NANOMYTE® TC-5001-coated structures provide significant corrosion protection while supporting power lines in service. The coating has been successfully demonstrated to protect electrical grid components still in service for several months to date.

Hardware Components

Various TC-5001-coated nuts, bolts, and screws were exposed outside for 5 continuous months and showed no visible signs of corrosion.

To the right is a pair of galvanized steel screws after 5 months of outside exposure. The uncoated screw (left) shows the emergence of white rust on the threads while the coated screw (right) is still protected.

Ease of Application and Curing

TC-5001 is amenable to dipping, brushing, and spraying. The ease of application of the coating is illustrated in the following video: Applying TC-5001

Methods of Application

  • Spraying: The coating is applied on clean surfaces using a commercial high volume, low pressure (HVLP) spray gun. Touchup spraying can be carried out to protect small pieces or tight locations using a touch up sprayer.
  • Rolling: Coating is done in a cross-pattern; left to right, then up and down as quickly as possible since the coating dries quickly.
  • Brushing: Brush application is carried out in a cross-pattern; up and down, then left to right.

.

Faster Curing

A new development that was requested by metal finishers was to accelerate the curing of TC-5001. For applications requiring faster cure times, the coating can be brought to “dry to the touch” conditions in a matter of 5 to 10 seconds with thermal curing at 150°C to 200°C. This facilitates easy incorporation of the coating in a production line with continuous moving parts on a conveyer. Once the coating is dry to touch (partially cured), subsequent coatings can be applied and cured together.

NANOMYTE® SuperCN Plus – A New Generation of Durable Superhydrophobic Coatings

March 26, 2014

Somerset, New Jersey – NEI Corporation announced today that it has introduced NANOMYTE® SuperCN Plus – a functionally graded coating that imparts superhydrophobic properties to the underlying substrate while providing greater abrasion resistance compared to existing superhydrophobic coatings. Surfaces treated with SuperCN Plus force liquids to bead up and roll off, shedding water instantly and leaving the surface completely dry. SuperCN Plus can be applied to a variety of substrate materials, including plastics, metals, glass, painted surfaces, and fabrics.

NANOMYTE® SuperCN Plus consists of a hard and abrasion resistant outer layer that transitions to a softer material closer to the substrate. Such a functionally graded coating represents a major advancement in the state of the art and is in sharp contrast to monolithic superhydrophobic coatings that consist of a relatively soft material that is easily abraded or rubbed away.

Both panels above were coated with superhydrophobic coatings and subjected to equal abrasion conditions. The panel on the left (commercial coating) shows abrasion marks, while the panel on the right (SuperCN Plus) shows no visible signs of wear.

Figure 1 – Both panels above were coated with superhydrophobic coatings and subjected to equal abrasion conditions. The panel on the left (conventional off-the-shelf coating) shows abrasion marks, while the panel on the right (SuperCN Plus) shows no visible signs of wear.

Superhydrophobic coatings rely on creating and maintaining a composite of micro and nano-sized surface structures that work together to trap a layer of air that can repel most liquids. Off-the-shelf superhydrophobic coatings tend to have poor durability because they are unable to protect these delicate surface structures from abrasion, resulting in rapid loss of superhydrophobicity. Due to the graded structure, SuperCN Plus maintains its superhydrophobicity and high contact angle even after moderate damage. Additionally, it exhibits good adhesion to the substrate.

Surfaces treated with SuperCN Plus show water contact angles as high as 165°. After moderate abrasion, where traditional superhydrophobic coatings begin to show significant damage and delamination, SuperCN Plus remains intact and has been shown to preserve its superhydrophobicity with contact angles over 158°.

Figure 2 – Water droplets on a metal substrate surface coated with NANOMYTE® SuperCN Plus, showing a high contact angle > 150°.

Figure 2 – Water droplets on a metal substrate surface coated with NANOMYTE® SuperCN Plus, showing a high contact angle > 150°.

Since the superhydrophobic coating is enabled by innovations in both process and materials, NEI is currently offering in-house coating services for industrial applications wherein customers can send parts of any geometry and size. The turnaround time is expected to be no more than 3 – 5 business days. If needed, the modular Super CN Plus coating process can be transferred to the OEM site.

New Self-healing Anti-corrosion Coating for Zinc-Plated & Galvanized Steel

March 11, 2014

<< Recent NEI News

Somerset, New Jersey – NEI Corporation recently introduced NANOMYTE® TC‐5001, a nanotechnology-enabled, single component, clear coating that significantly improves the corrosion resistance of zinc‐plated and hot‐dip galvanized (HDG) steel. It is amenable to dipping, brushing, and spray coating. The new coating technology is designed to protect zinc‐plated and galvanized steel surfaces from rusting under severe environmental and operating conditions. Applications of the coating technology include protecting outdoor structures (e.g., electrical grid structures, street lights, and lattice beams), hardware (e.g., rods, pipes, nuts, bolts and screws), automotive components and farming equipment. The dense barrier coating can be used as a standalone coating, as well as in combination with NANOMYTE® PT‐100, a self‐healing conversion coating. In salt‐spray tests (SST, ASTM B117), uncoated zinc‐plated steel bolts exhibited white rust in 24 hours and red rust after 168 hours. In contrast, the NANOMYTE® coating provided significant corrosion protection, even after 504 hours of SST. Typically, TC-5001-coated parts show no white rust even after 1000 hours and no red rust even after 1200 hours. SST can be used in conjunction with field testing and online life predictors for coatings on HDG, as prescribed by the American Galvanizers Association (AGA).

NEI introduces NANOMYTE® SR-100EC – An Easy-to-Clean, Scratch Resistant Coating

August 20, 2013

<< Recent NEI News

Somerset, New Jersey – NEI Corporation announced today that it has introduced a transparent, micron-thick coating that provides both scratch resistance and easy-to-clean properties to surfaces. The waterborne SR-100EC coating can be applied to plastics such as polycarbonate, PMMA, PET, polyurethane, epoxy, as well as metals such as stainless steel, aluminum, titanium, brass and chrome. The surface treatment is mechanically stable, is highly repellent to water and oils, and it enhances lubricity. By applying SR-100EC on the surface of components, soil and liquids simply slide off the surface, thereby helping prevent deposits and extending the time between cleanings.

The NANOMYTE® SR-100EC coating is based on a patent pending, water-based coating composition comprised of functionalized perfluoropolyethers (PFPEs). Although PFPEs are known for their non-stick and lubricating properties, it has been a major technical challenge to incorporate them into a stable formulation that can lead to a coating with sufficient adhesion to various substrates. NEI’s SR-100EC formulation overcomes this stability issue. Additionally, while PFPE-based, easy-to-clean coatings currently on the market generally form very thin (< 100nm) coatings, SR-100EC coatings have a thickness of 2-5 microns, thereby creating a more mechanically stable coating that cannot easily be removed by abrasion, harsh cleaners or chemicals.

“The development of SR-100EC was spurred by a need expressed by many of our customers, who wanted a relatively thin coating that is highly hydrophobic and oleophobic, but also hard and transparent,” says Dr. Ganesh Skandan, CEO of NEI Corporation. “SR-100EC represents a significant addition to NEI’s portfolio of coating products.”

SR-100EC is easy to use and is ideally suited for optical lenses, touch screen protectors, stainless steel appliances, hand rails, and faucets. The liquid coating solution can be applied by dipping, spraying, roll or flow coating and is available in 1, 5, and 55 gallon quantities. NEI also offers in-house coatings services for customer parts. Additionally, NEI provides coatings development services wherein coating formulations are created to address specific customer requirements.

For more information, the materials specification sheet for NANOMYTE® SR-100EC can be found here.

NANOMYTE® PT‐60C – A New Electrically Conducting Corrosion Resistant Coating

May 6, 2013

<< Recent NEI News

Somerset, NJ – NEI Corporation announced today that it has introduced a chromate‐free, electrically conducting conversion coating that significantly improves the corrosion resistance of lightweight metal alloy components. NEI’s NANOMYTE® PT‐60C is specifically formulated for the surface treatment of lightweight metal alloys, such as aluminum or magnesium, used in the electronics industry. PT-60C provides excellent corrosion protection, while simultaneously providing surface and bulk electrical conductivity. The unique “self-repairing” nature of PT-60C overwhelms the galvanic corrosion caused by the electrical conductivity of the coating. Additionally, PT-60C is a waterborne coating solution.

Coatings on lightweight metal components get damaged over time due to contact and spring impact. The damaged areas are sites of potential galvanic and general corrosion. In order to maintain electrical conductivity in grounding and electromagnetic interference (EMI) shielding, corrosion in the contact areas needs to be inhibited. PT-60C provides the necessary corrosion protection. In contrast to currently used coatings, which are either not sufficiently conducting or do not provide adequate corrosion protection, PT-60C provides an easy-to-use alternative with enhanced performance.

The applicability of PT-60C has been demonstrated specifically for magnesium alloys, which have a high tendency to corrode. PT-60C was compared to two conventional treatment technologies – electroless nickel plating and stannate immersion. In salt‐fog exposure experiments (ASTM B117), magnesium AZ91D panels coated with PT‐60C showed minimal corrosion, even after 10 days (240 hours). In contrast, AZ91D panels with electroless nickel and stannate immersion exhibited general and galvanic corrosion after only 24 hours.

Applications of PT-60C include CD/DVD/Blu-ray players, smart phones, housings of digital cameras, cell phones, the exterior and base of computer notebooks, and handheld devices – places where metallic chassis, cases and frames protect electronic circuitry and sensitive LCD displays.

PT-60C is a single component, waterborne solution. Metal panels can be coated by simple immersion, resulting in a microns thick standalone coating. The liquid is available in 1, 5 and 55 gallon quantities. “Our pretreatments, primers, and topcoats are innovative drop-in solutions for various metal finishing needs. PT-60C represents our ability to engineer a coating solution that meets a specific application requirement,” said Dr. Fred Allen, Group President of Anticorrosion Coatings at NEI Corporation.

NEI Corporation Launches New Anticorrosion Coating Product to Protect Steel and Aluminum in Extremely Harsh Environments

October 9, 2012

<< Recent NEI News

Somerset, NJ – NEI Corporation introduced today a new flexible coating product specifically designed to protect oxidizing steel and aluminum exposed to corrosive chemicals or harsh environmental conditions. The technology was developed in New Zealand and has been used throughout the South Pacific for over 40 years. In collaboration with the Goldseal Group, NEI is now offering the product for sale in North America under the name NANOMYTE® TC‐3001. Unlike conventional paint, which will chip or crack when exposed to stress from vibration, expansion, or flexing, TC‐3001 will move, bend and conform to the substrate that it covers. The coating can last 10 to 15 years, or more, in the field with little or no maintenance.

NANOMYTE TC‐3001 is unique in that traditional solvents and binders are replaced by a high‐solids carrier. The material is heated until liquefied, then applied by hot airless spray. The result is a smooth, uniformly thick coating. Cracks and crevices in pre‐existing paint, and even spalled concrete, can be filled as the metal surface is covered. TC‐3001 is able to protect the metal substrate by adapting to changing environmental conditions. The coating maintains its resiliency and structural integrity over time, better than conventional anticorrosion paints and coatings.

TC‐3001 is formulated as a single pack, single application encapsulating barrier coats that are corrosion neutralizing and lubricating. The compound is a niche solution in extreme environments, often associated with aggressive chemicals and marine deposits such as encountered in factories and refineries, boats and barges, as well as on bridges and wharfs.

Adding this new coating product to its portfolio is part of NEI’s efforts to develop corrosion resistant coating systems, including pretreatments, primers and topcoats, to protect customers’ metal assets. The coatings are economical, easy to use and provide excellent corrosion resistance compared to state‐of‐the art offerings.

“We are excited by our collaboration with the Goldseal Group because it gives us the chance to offer our customers a new corrosion solution backed by 40 years of field results,” said Dr. Fred Allen, President of the Anticorrosion Coatings Division at NEI Corporation. “TC‐3001 is not a replacement for paint, but a proven alternative for use in extremely harsh corrosive environments.” The announcement was made by Dr. Allen at the North American Corrosion Engineers (NACE) Eastern Area Conference in Iselin, NJ.

NEI Corporation Introduces Self‐Healing Anti‐Corrosion Coating for Zinc‐Plated and Galvanized Steel

July 19, 2012

<< Recent NEI News

Somerset, NJ – NEI Corporation introduced today a nanotechnology‐enabled, two‐layer coating that significantly improves the corrosion resistance of zinc‐plated and hot‐dip galvanized (HDG) steel. The NEI coating is a drop‐in replacement for trivalent chromium. The coating process consists of first applying NANOMYTE® PT‐100, a self‐healing conversion coating, followed by NANOMYTE® TC‐5001. The latter is a barrier coating, designed to work synergistically with PT‐100. Both PT‐100 and TC‐5001 are liquid coating formulations that are amenable to dip coating, brushing, and spray coating. The new NANOMYTE coating technology is designed to protect zinc‐plated and galvanized steel surfaces from rusting under severe environmental and operating conditions. In salt‐fog exposure experiments (ASTM B117), NANOMYTE‐coated, zinc‐plated steel panels showed no white rust after 840 hours; no red rust was observed even after 1200 hours. In contrast, non‐coated, zinc‐plated panels exhibited white rust in 24 hours and red rust after 168 hours in the salt‐fog chamber. Salt‐spray testing can be used in conjunction with field testing and online life predictors for coatings on HDG, as prescribed by the American Galvanizers Association (AGA).

The new technology is part of NEI’s efforts to develop corrosion resistant coating systems, including pretreatments, primers and topcoats that protect steel, aluminum and magnesium from corrosion. The coatings are economical, easy to use, and provide excellent corrosion resistance compared to state‐of‐the art offerings. “Our thin, double coat solution for zinc‐plated and HDG steel represents a significant advancement in the state‐of‐the‐art that could eliminate the need for using thicker primers and topcoats,” said Dr. Fred Allen, President of the Anticorrosion Coatings Division at NEI Corporation. “The market focused activities of NEI are a key to serving the needs of customers who require high‐performance anticorrosion coatings. Our goal is to engage customers as partners in developing new corrosion‐resistant coating products.”
