Silane Coupling Agent

Methacryl Silane

Methacryl silane, often referred to as gamma-methacryloxypropyltrimethoxysilane or MPS (3-methacryloxypropyltrimethoxysilane), is a versatile chemical used in various industries, particularly in materials science and surface modification. Methacrylate silane acts as a coupling agent that bonds organic materials (like polymers) to inorganic substrates (such as glass, metals, or ceramics) through its reactive methacrylate group and silane moiety.
