Silane Coupling Agent A-174 (γ-Methacryloxypropyltrimethoxysilane, MPS)
CAS Number: 2530-85-0
Silane Coupling Agent A-174 (KH-570, MPS) is a methacrylate-functional silane used to improve adhesion between UV-curable, acrylic, and unsaturated polyester resins and inorganic substrates. The methacrylate group copolymerizes with acrylic monomers during UV or peroxide cure while the trimethoxysilyl group bonds to glass, silica fillers, and metal surfaces. It is widely used in UV adhesives, acrylic sealants, dental composites, and glass fiber-reinforced polymer composites.
