3-(Methacryloxy)propyltrimethoxysilane Description
3-(Methacryloxy)propyltrimethoxysilane is a high-performance organosilane coupling agent with excellent solubility, freely dissolving in various organic solvents. It is highly susceptible to hydrolysis and easily condenses into polysiloxane under conditions of high temperature, light exposure, or in the presence of peroxides. This compound is widely used in coatings, adhesives, composites, and UV-curable resins, enhancing adhesion, weather resistance, and mechanical properties. Its reactive methacryloxy group enables strong chemical bonding between organic polymers and inorganic substrates, making it ideal for advanced material applications.
