Hydrophilic spreading
Condensed droplets spread into a more continuous film to reduce light scattering.
HYDROPHILIC SURFACE TECHNOLOGY
Anti-fog coatings for clear and reliable visibility
Manage condensed water by controlling how it spreads across lenses, covers, windows and optical surfaces.
FUNCTIONAL MECHANISM
Anti-fog performance begins with the condensation environment
A useful material system balances water spreading, transparency, adhesion, cleaning behavior and the amount of condensation expected in service.
Transparent appearance
Film formation and compatibility must be controlled on the actual clear substrate.
Use and cleaning durability
Maintenance method and repeated condensation can be as important as initial performance.
STANDARDS ALIGNMENT
Standards-aligned anti-fog verification
NFG materials can be configured for safety eyewear, ski goggles, swimming eyewear and transparent components according to finished-product use, substrate and customer specification.
Occupational eye and face protection
The current route uses ISO 18526-2:2020 test methods with ISO 16321-1:2021 finished-product requirements.
Sports eyewear
Ski goggles align with ISO 18527-1:2021; swimming eyewear aligns with ISO 18527-3:2020 and its 2025 amendment.
Customer-retained European methods
EN 168:2001 and EN 174:2001 are withdrawn, but their anti-fog methods can be retained where cited by an existing drawing or contract.
Scope of conformity: NFG materials can support the applicable anti-fog requirement. Conformity of a complete spectacle or goggle depends on testing all applicable finished-product requirements.
APPLICATIONS
Representative applications
The NFG series covers several application directions, each requiring its own component-level confirmation.
Safety and sports optics
Protective eyewear, face shields, cycling lenses, snow goggles and swimming goggles.
Lighting and observation
Vehicle lighting, camera optics, machine windows and transparent covers.
Refrigeration and flow control
Cold-display windows and hydrophilic surfaces where controlled water spreading is useful.
