Coupling agent 3-Methacryloxypropyltrimethoxysilane / KH-570 CAS 2530-85-0

3-(Trimethoxysilyl)propyl methacrylate, often abbreviated as TMSPMA, also known as KH-570, A-174, Z-6030 or KBM-503, is a monomer that combines the properties of a methacrylate group and trimethoxysilyl groups. It is primarily used as an adhesion promoter and coupling agent in various industries.

TMPSM is valued for its ability to improve the adhesion between dissimilar materials. It can form strong covalent bonds with surfaces such as glass, metals, ceramics, and polymers through the reactive trimethoxysilyl groups. The methacrylate functionality allows it to participate in polymerization reactions, making it suitable for the production of polymer-based materials and coatings.

The presence of TMPSM in formulations enhances the compatibility and adhesion between different materials, resulting in improved mechanical strength, durability, and resistance to environmental factors. It is commonly utilized in applications such as adhesives, sealants, coatings, composite materials, and surface modification treatments.

TMPSM offers several advantages, including improved adhesion, enhanced chemical and thermal stability, and compatibility with a wide range of substrates. It is also known for its low volatility and good hydrolytic stability, allowing for long-term performance in various environments.
