Anti Fog Coating

Antifog Coating is a hydrophilic polymer based coating used to improve visibility of transparent lenses, windows, and domed crystals by preventing condensation from ambient moisture. The coating is liquid based, and after application forms a permanent transparent coating approximately .00035" thick.

Anti-fog coating can be applied to any substrate, typically glass and thermoplastic by a variety of methods. These include dip coating, spin coating, spray coating, and flow coating. Anti-fog plastic films are also available for laminating to glass substrates for impact resistance. NGC will help determine the best combination of coatings and processes to meet the customer's need for price and performance.

Anti-fog coatings are most often required for applications such as marine gauges, heavy construction equipment, automotive mirrors and instrument panels, aerospace glazing, military night vision lenses, outdoor vehicles such as ATVs and RVs, and the optics industry.

Hardcoating is a polysiloxane based liquid coating used to prevent abrasion and scratching of non-glass materials such as injection molded polycarbonate gauge covers. It can also be used to seal and protect the surface of specialty glass products that may be susceptible to environmental degradation. Hardcoating can be combined with anti-fog chemistry to yield a coating that shares both properties. Finished coating thickness is approximately .0004" thick.

Application methods are identical to those used for Anti-fog coating.

End-uses are similar to anti-fog applications, with the additional of opaque substrates such as automotive trim, where abrasion resistance is desired.

UV Coating is a custom blended coating using a carrier material such as the silicone hard coating mentioned above, loaded with UV absorbers that block the transmission of harmful ultraviolet waves. The coating can be applied to glass or plastic substrates.

Application methods are identical to those used for Anti-fog coating.

End uses include solar energy applications, outdoor optics, aerospace and military products, or any application that is exposed to high amounts of UV energy.
