3-(Dimethoxymethylsilyl)propyl Methacrylate: Properties and Applications

INNO Specialty Chemicals, a leading manufacturer and supplier of specialty chemicals based in China, offers a wide range of products including 3-(dimethoxymethylsilyl)propyl methacrylate, also known as Silane coupling agent KH-572, DOWSIL Z-6033, Shin-Etsu KBM-502, and other synonyms. This article aims to provide an overview of the properties and applications of this versatile chemical compound.

Properties:

3-(Dimethoxymethylsilyl)propyl methacrylate is a colorless to pale yellow liquid with a molecular weight of 248.38 g/mol, a density of 1.03 g/mL at 25°C, a boiling point of 101-102°C at 1.33 kPa, and a refractive index of 1.433-1.435 at 25°C. It is soluble in most organic solvents, such as ethanol, acetone, and toluene, but insoluble in water.

The chemical structure of 3-(dimethoxymethylsilyl)propyl methacrylate contains a methacrylate group and a silane group, which makes it a bifunctional compound. The methacrylate group is capable of polymerization and forms strong covalent bonds with other methacrylate-based monomers or polymers, while the silane group can react with inorganic surfaces, such as glass, ceramics, metals, and minerals, through a condensation reaction to form a stable chemical bond. Therefore, 3-(dimethoxymethylsilyl)propyl methacrylate is a highly effective coupling agent for improving the adhesion, wetting, and compatibility between organic and inorganic materials.

Applications:

3-(Dimethoxymethylsilyl)propyl methacrylate has a wide range of applications in various industries, such as coatings, adhesives, sealants, composites, electronics, and construction.

In coatings, 3-(dimethoxymethylsilyl)propyl methacrylate can be used as a crosslinking agent, a reactive diluent, or a surface modifier to enhance the durability, scratch resistance, and weatherability of the coatings. It can also improve the adhesion of the coatings to various substrates, such as metal, plastic, and wood.

In adhesives and sealants, 3-(dimethoxymethylsilyl)propyl methacrylate can act as a coupling agent, a crosslinking agent, or a reactive diluent to improve the bonding strength, water resistance, and thermal stability of the adhesives and sealants. It can also increase the adhesion of the adhesives and sealants to difficult-to-bond substrates, such as glass, ceramics, and metals.

In composites, 3-(dimethoxymethylsilyl)propyl methacrylate can be used as a coupling agent or a surface modifier to enhance the interfacial adhesion between the reinforcing fibers or particles and the matrix resin. It can also improve the mechanical properties, such as tensile strength, flexural strength, and impact resistance, of the composites.

In electronics, 3-(dimethoxymethylsilyl)propyl methacrylate can be used as a dielectric coating or a surface modifier for electronic components, such as printed circuit boards and semiconductors. It can also enhance the adhesion and moisture resistance of the coatings.

In construction, 3-(dimethoxymethylsilyl)propyl methacrylate can be used as a surface modifier for concrete and mortar to improve the adhesion, water resistance, and durability of the structures. It can also act as a water repellent agent for masonry and stone.

Conclusion:

3-(Dimethoxymethylsilyl)propyl methacrylate is a versatile chemical compound with excellent properties and a wide range of applications in various industries. Its unique bifunctional structure makes it a highly effective coupling agent for improving the interfacial adhesion between organic and inorganic materials. As a leading manufacturer and supplier of specialty chemicals, INNO Specialty Chemicals is committed to providing high-quality products and professional services to its customers worldwide.
