Anti-Fog Coatings
Tired of frustrating fog obscuring your vision? Anti-fog coatings are specially engineered surface treatments designed to prevent the condensation of water vapor, ensuring lasting clarity in a variety of demanding environments. From enhancing safety in eyewear and automotive windshields to maintaining the performance of optical instruments and protective screens, anti-fog technology offers a clear advantage across numerous applications.
The Choice is Clear: NANOMYTE® SAF-100
NANOMYTE® SAF-100 coated polycarbonate resists fogging over hot water (left) and upon being removed from a freezer (right).
NANOMYTE® SAF-100 is an advanced optical-grade coating that provides both exceptional scratch resistance and reliable anti-fog properties for a variety of surfaces. This innovative coating builds upon the proven durability of NEI’s patented NANOMYTE® SR-100 scratch-resistant technology. We’ve enhanced this base with unique amphiphilic compounds that are permanently integrated into the coating’s structure. This creates a robust, three-dimensional network at the molecular level, resulting in outstanding mechanical durability. The significant benefit of this advanced design is that the anti-fog performance is retained even after repeated washing, ensuring long-lasting clarity.
Features & Benefits:
- Long-Lasting Anti-fog Performance: Effectively prevents fogging even in challenging conditions, providing continuous clear vision.
- Exceptional Durability & Washability: Maintains its mechanical integrity and anti-fog properties even after repeated washing with soap and water, ideal for permanent applications.
- Superior Scratch and Mar Resistance: Significantly improves the resistance of coated plastic substrates to scratches and marring, extending the life of the surface.
- Optical Clarity: Thin and highly transparent, minimizing any optical distortion for optimal viewing.
- Hydrophilic Action: The coating’s hydrophilic nature attracts water molecules, causing them to spread out in a thin, invisible film instead of forming vision-obscuring droplets (fog).

Coating Overview
NANOMYTE® SAF-100
NANOMYTE® SAF-100 is a permanent, optically clear anti-fog coating. The novel coating passes EN 168 (Personal eye-protection. Non-optical test methods) for Mist Retardant Anti-fog Coatings and also exhibits anti-frost properties. Applied via dip or flow coating and requiring thermal curing, the hydrophilic coating exhibits excellent abrasion resistance and can be easily washed without compromising its anti-fog properties. The two-component liquid system is engineered for lasting fog prevention across various applications.
Physical Characteristics:
- Product Form: Two-part liquid coating solution
- Color: Part A – Translucent; Part B – colorless
- Mix Ratio (A:B): 10:1 (by weight)
- Solvent for Dilution: PM Glycol Ether
Technical Data:
- Induction time: 30 minutes
- Dry Film Thickness: 5 – 10 µm (recommended)
- Pencil Hardness: HB
- Water Contact Angle: < 5°
- Water Resistance: Maintain anti-fog function after immersion in DI water for 24 hours
- Abrasion Resistance: Δ Haze < 3% (ASTM D1044 Taber abrasion test, polycarbonate substrate, CS-10F wheels, 500g load, 500 cycles)
- Anti-fog Performance:
- Breath Fog Test – No fogging
- Hot Water Test (80°C) – No fogging in 1 minute
- Freezer Test – No fogging after transferring from a freezer (-20°C) to a room temperature environment having relative humidity <45%

Coating Application
Coating Application
Coating application should be performed in a clean environment to minimize surface defects. Ensure surfaces to be coated are clean and dry and apply a primer if necessary (such as polymer substrates). NEI supplies a primer product, NANOMYTE® SR-Primer, which works well with a range of plastics. The primer may be applied by dipping, flowing or spinning. Allow SR-Primer to dry in air for at least 30 minutes before coating application.
To make the coating solution, combine SAF-100 Part A and Part B at a 10:1 weight ratio and mix well by stirring briefly. The coating may be applied by spraying, dipping, flowing, rolling, or spinning. Filter the coating liquid with 0.1 μm filter to avoid speckles in the coating. The as-received coating at the above mixing ratio is good for dip coating. Dilute the mixed solution with 10% PM glycol ether for flow coating. Although the mixed coating solution is stable indefinitely, it is recommended to use the solution within 24 hours after mixing for the best performance.
Curing Conditions:
NANOMYTE® SAF-100 is thermally cured at an elevated temperature. Recommended curing conditions:
- PMMA: 2 hours at 85°C
- Polycarbonate: 1 hour at 120°C
- Other: 30 minutes at 150°C (for substrates that can withstand high temperatures)
Shorter cure times / reduced temperatures may also be used depending on surface properties and performance requirements. Test samples for desired performance when deviating from recommendations.
