Fluorine-based anti-fingerprint and anti-soil coating materials used as cover glass for touch panels in smartphones and car navigation systems.
The anti-fouling coating agent "NB05" for glass and optical products can form a highly durable fluorine-based functional film by treating the surfaces of soda glass, aluminosilicate glass, and films for optical products. ● Features of NB05 - Excellent water and oil repellency: contact angle with pure water over 110°, oleic acid 78° - Improved slip: dynamic friction coefficient 0.04 - Extremely thin film thickness of less than 10nm - Colorless and transparent film with minimal impact on the optical properties of the product - High durability recognized by major manufacturers both domestically and internationally (Sliding test with steel wool: contact angle over 100° after 9000 cycles at 1kg/cm² on glass) - Usable with various application methods such as spraying, dipping, hand painting, and spin coating * For those interested in the spraying method, we provide a dedicated spray gun and application conditions.
