NEI Corporation introduces UV-Protect Technology to NANOMYTE® Coating Line

March 7, 2018

Somerset, New Jersey (USA) – NEI Corporation announced today that it has introduced UV-Protect (UVP) technology to formulate enhanced versions of its popular NANOMYTE® coating products, which offer unique functionalities in coatings with unparalleled durability. The NANOMYTE® line of protective coatings and surface treatments provide tailored functionalities, such as hydrophobicity, superhydrophobicity, oleophobicity, superoleophobicity, self-healing, fog resistance, self-cleaning (or easy-to-clean), scratch resistance, anti-corrosion, and anti-icing. They have found wide applicability in the industrial and automotive markets for their versatility and ability to be applied to a variety of surfaces – including glass, plastic, fiber-composite, metal, and ceramic. UVP technology imparts enhanced protection from the effects of sun and weather exposure to maintain the unique properties of their coating products when subjected to long-term outdoor exposure.

The newly-introduced product lineup consists of:

UVP Technology Brief (pdf)

NANOMYTE® coating products with UVP technology have demonstrated their ability to endure a minimum of 1,000 hours of weatherability testing per ASTM D4587, “Accelerated Weathering under Fluorescent UV-Condensation Exposure.” The testing was performed in a QUV chamber under the conditions specified in ASTM G154, Cycle 1, the most commonly used exposure cycle designed to simulate severe outdoor service conditions. The UVP functionality has been incorporated into each coating system without degrading other performance characteristics or ease of application. The cured film is both inherently resistant to the sun’s UV radiation, as well as capable of providing UV protection for the underlying surface. This, for example, allows the NANOMYTE® MEND product line to maintain excellent gloss and appearance in outdoor applications, such as automotive coatings. Polymer and composite materials can be particularly sensitive to the effects of UV exposure, which can have a variety of undesirable effects, beginning at the surface and often spreading throughout the bulk of the material. Surface attack immediately begins to compromise coating adhesion, eventually resulting in cracking and peeling. UV-degraded materials may also change colors, often resulting in the familiar yellowing of plastics and lose mechanical strength, making them prone to failure. UVP coatings block UV radiation, which protects surfaces by preserving coating adhesion and aesthetics, and prevents further penetration of UV light which can compromise the material’s strength and appearance.

Outdoor exposure can present additional challenges for surfaces to resist buildup of dirt, airborne contaminants, corrosion, and even ice. NEI’s line of durable protective topcoats, formulated as one-component, ambient-cure systems for ease of use, now offer UVP technology to extend their performance and shield sensitive surfaces. NANOMYTE® SR-500EC-UVP can protect a wide variety of surfaces from the effects of outdoor exposure, coupled with an easy-to-clean functionality with enhanced weatherability. For surfaces prone to icing, NANOMYTE® SuperAi-UVP not only helps keep surfaces clean, but also enhances their ability to shed ice buildup, all while providing excellent protection from the elements. Both of these coatings can maintain excellent hydrophobicity, with a static water contact angle of 100 – 105°, even after 2,000 hours of QUV exposure, while NANOMYTE® SuperAi-UVP maintains a low ice adhesion value of less than 1 psi after more than 1,000 hours of exposure. NANOMYTE® TC-4001-UVP and TC-5001-UVP have been optimized for metals to form a hard, durable coating with excellent barrier properties to prevent moisture penetration and corrosion.

NEI’s coating products featuring UVP technology can be applied by conventional processes, such as dipping, brushing or spraying. NEI also offers in-house coating services for customer’s parts, as well as coating development services, wherein coating formulations are created to address specific customer requirements. The development of NANOMYTE® UVP functional coatings has come about as a result of NEI’s capabilities in creating functionalized nanocomposite coatings. In addition to imparting protective and aesthetic properties, NANOMYTE® coatings lead to gains in productivity and efficiency and therefore can be used in many applications that traditionally have not used paints or coatings.

NEI Announces Allowance of Two New Patents to Its Portfolio of Functional Coatings

February 7, 2017

Somerset, NJ (USA) – NEI Corporation announced today that the US Patent and Trademark Office (USPTO) has recently issued a notice of allowance to the company on two patent applications; one for a durable highly hydrophobic coating and the other for an adhesion promoting surface treatment. These patents complement NEI’s portfolio of patents pertaining to superhydrophobic, self-healing, and abrasion resistant coatings. With the allowance of seven patents, and the introduction of an array of coating products, NEI’s concerted efforts to develop and implement practical, multi-functional coatings have now come to fruition.

There is great interest in functional coatings, for both industrial and consumer applications, where the coating or surface treatment provides functionalities beyond the usual protective and aesthetic properties. For example, self-healing coatings autonomously repair damage, hydrophobic coatings are able to vigorously repel water droplets, oleophobic coatings prevent “oil” molecules from sticking to the surface, self-cleaning or easy-to-clean coatings minimize or eliminate the need for chemicals during washing, and adhesion promoter surface treatments enable an ultra-strong bond between the primer and the surface. Commercial products to date have met with limited success because they are not engineered to meet all of the functional performance requirements that an application requires. NEI’s patented and patent-pending technologies address this market need.

The recently allowed patent application describes durable hydrophobic coating compositions that are highly desirable for numerous applications, as they impart easy-to-clean and stain-resisting properties to surfaces. For aesthetic reasons, there is also a need for a thin, transparent, easy-to-clean coating that does not add excess weight and does not change the appearance of the substrate to be coated. The patented compositions are comprised of functionalized perfluoropolyethers (PFPEs), which are known for their non-stick and lubricating properties. It has been a major technical challenge to incorporate PFPEs into a stable formulation that can lead to a coating with sufficient adhesion to various substrates. The patent claims transparent and homogeneous compositions that overcome the stability and adhesion issues. The compositions result in a micron-thick, durable hydrophobic coating that cannot easily be removed by abrasion, harsh cleaners, or chemicals. The patent is the basis for NEI’s hydrophobic coating products, NANOMYTE® SuperCN and SR-100EC.

The adhesion promoter patent application describes a chromate-free, surface pretreatment composition. The environmentally-friendly, waterborne pretreatment promotes the adhesion between a metal substrate and an overlying paint layer by acting as a “double‐sided bonding agent,” while at the same time improving corrosion resistance. The novel composition comprises organo-functional silanes but functions differently from traditional silane treatments. The composition results in a thin film coating having a graded structure, i.e., an inorganic oxide layer that bonds strongly with steel and a loosely crosslinked top layer containing functional groups that can further crosslink with paint overlay. The new technology is valuable to applicators who paint metal structures, such as bridges, ships, and other steel structures. It is also applicable to industrial painting operations, such as coil and spray coatings. The patented chromate‐free pretreatment for steel, offered commercially as NANOMYTE® PT-20, represents a significant advancement in the state‐of‐the‐art for corrosion resistant technologies.
