3-Methacryloxypropyltrimethoxysilane CAS No. 2530-85-0: A versatile silane coupling agent

3-Methacryloxypropyltrimethoxysilane CAS No. 2530-85-0 (3-MPS) is a versatile silane coupling agent that is used in a variety of applications. It is a hydrophobic monomer that has an additional functional group of acrylate, which facilitates grafting polymerization on plastic surfaces. 3-MPS undergoes first-order kinetic polymerization to form polyTMSPMA, which is a moisture stable polymer.

3-MPS is used in a variety of coating, adhesive, and sealing agents. It provides excellent adhesion and durability, and it can also improve the water resistance of these products. 3-MPS is also used in the preparation of polymers, such as polystyrene latex, which have silanol groups. These silanol groups can react with other functional groups, such as hydroxyl groups, to form cross-linked networks.

3-MPS is a safe and effective product that has a wide range of applications. It is non-toxic, non-flammable, and non-corrosive. 3-MPS is also biodegradable, making it an environmentally friendly choice.
