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.
