DYNASLYAN F 8261 is a bifunctional silane possessing hydrolyzable inorganic ethoxysilyl groups and a fluoroalkyl chain. DYNASYLAN F 8261 acts as a surface modifier on mostly hydroxyfunctional substrates. It can form chemically and mechanically stable coatings which exhibit a thickness of only a few nanometers. Suitable substrates include glass, silica, quartz powder, sand, sandstone, cristobalite, wollastonite, mica, kaolin, talc, and other silicate surfaces. DYNASYLAN F 8261 treated surfaces have properties like easy-to-clean, water-repellent, UV-resistant which are highly beneficial in applications where durability and protection from external elements is required. DYNASYLAN F 8261 provides long lasting performance and protection to treated surfaces with minimal thickness.
