3-Methacryloxypropyltrimethoxysilane CAS 2530-85-0

Introduction

Silane coupling agent KH-570 is a widely used methacryloxysilane, and our company's brand is KT-R74. Its molecular structure has a methacryloxy functional group with an unsaturated double bond structure and three hydrolyzable methoxy functional groups. This dual reactivity allows silane coupling agent KH-570 to improve the bonding, adhesion and compatibility between inorganic materials (glass, metal, filler) and organic polymers (thermosetting resins, plastics, elastomers) through a two-way chemical reaction, thereby improving the mechanical properties of resin-based composite materials or improving the bonding strength and water resistance of resin coatings. At the same time, silane coupling agent KH-570 can also copolymerize with monomers containing unsaturated double bonds such as acrylic acid, methacrylic acid, vinyl acetate, styrene, etc., thereby giving the copolymer moisture curing and good adhesion and water resistance, etc. In different applications, silane coupling agent KH-570 can be used as a coupling agent, adhesion promoter, crosslinking agent, surface modifier of pigments and fillers, silicone modified graft copolymer monomer, etc.

Physical indicators

Application 

1. Silane coupling agent KT-R47 can improve the mechanical and electrical properties of glass fiber reinforced and inorganic filler-containing thermosetting and thermoplastic resins, especially those thermosetting resins (such as unsaturated polyesters, polyesters and acrylates) cured by active free radical mechanism, peroxide-cured rubber (EPR, EPDM, silicone rubber, etc.) and thermoplastic resins (including polyolefins and thermoplastic polyurethanes).
2. This product can significantly improve the dry and wet mechanical strength and electrical properties of unsaturated polyester composites filled with inorganic fillers (such as cast or die-cast artificial quartz stone, etc.).
3. Silane coupling agent KT-R47 can copolymerize with vinyl acetate, acrylic acid or methacrylic acid monomers to synthesize silane-modified polymers that can be cross-linked and cured at room temperature. Such polymers are widely used in coatings, adhesives and sealants to provide excellent adhesion and durability.
