3-(Methacryloyloxy)propyltris(trimethylsiloxy)silane（Cat No.:M088597）is a multifunctional organosilane used as a coupling agent, adhesion promoter, and surface modifier in polymer and coating formulations. It contains a methacrylate group capable of free radical polymerization and three trimethylsiloxy groups that enhance compatibility with silicone-based materials. This dual functionality makes it ideal for improving interfacial bonding between organic polymers and inorganic surfaces like glass, metal, or ceramics. Widely used in adhesives, sealants, and dental materials, it enhances durability, hydrophobicity, and chemical resistance in cured systems. It is typically supplied as a clear, low-viscosity liquid.
