Product Description
Silane Coupler G-570 (also known as γ-Methacryloxypropyltrimethoxysilane / 3-(Trimethoxysilyl)propyl Methacrylate, CAS 2530-85-0) is a clear, colorless to pale-yellow transparent low-viscosity liquid with a mild ester-like odor. As a bifunctional organosilane, it carries a polymerizable methacryloxy group on one end and three hydrolyzable methoxy groups on the other, enabling strong chemical bridging between organic polymer matrices (via radical cure, co-polymerization or grafting) and inorganic substrates (glass, metal, minerals, fillers) through silanol condensation. It delivers excellent adhesion promotion, moisture resistance, composite reinforcement and surface modification performance. Widely used as a coupling agent, adhesion promoter, reactive diluent and surface primer in fiber-reinforced composites, coatings, adhesives, sealants, wire & cable compounds and electronics encapsulation.
