DYNASLYAN VTEO is a bifunctional organosilane possessing a reactive vinyl group and a hydrolyzable inorganic triethoxysilyl group. It reacts rapidly with water and can remove even traces of moisture. This property makes DYNASYLAN VTEO suitable for preparing moisture-curing polymers. It improves properties like tear resistance, crack resistance, chemical resistance and abrasion resistance of polymers once crosslinked. DYNASYLAN VTEO also acts as an adhesion promoter for filled polymers, improving mechanical and electrical properties after exposure to moisture. It hydrophobizes filler surfaces, improving compatibility and properties of filled materials. Surface treatment with DYNASYLAN VTEO enhances adhesion, corrosion resistance and scratch resistance of coated substrates.
