γ-methacryloxypropyltrimethoxysilane KH-570

Corresponding foreign brands: American Union Carbide Corp :A-174TM

The main chemical components: CH₂C(CH₃)COO(CH₂)₃Si(OCH₃)₃
Chemical Name: γ- methacryloxypropyl trimethoxy silane

Physical and chemical properties: This product is a colorless transparent liquid, Flash point Tag sealed cup (ASTM D93): 108℃, density: ρ (25℃): 1.045, boiling point (760mmHg): 255℃, refractive index ND 25℃ : 1.429 , Molecular weight: 248.4g/mole. It is soluble in methanol, ethanol, isopropanol, acetone, benzene, toluene and xylene. After hydrolysis, it can be dissolved in water with pH 4.0 under stirring. After hydrolysis, methanol is produced.

Application areas: plastic products, rubber products, paints, inks, composite materials, magnetic materials, adhesives, casting, synthetic amino silicone oil, etc.

Application object:

1. Resins: phenolic, urea-formaldehyde, furan, nylon, polyurethane, unsaturated polyester, alkyd resin, acrylic resin and natural rubber, styrene-butadiene rubber, neoprene rubber, nitrile rubber, EPDM, PE, PP, PVC, S BS, etc.
2. Fillers: quartz, talc, kaolin, mica, white carbon black, wollastonite, glass fiber, Al(OH) 3 , Mg(OH) 2 , metals and their oxides, etc.

Product Features:

1. Treating the glass fiber yarn with a wetting agent (containing film-forming agent, lubricant and antistatic agent) containing the silane coupling agent KH-570 can improve the mechanical strength of the glass fiber yarn-reinforced composite material.
2. Improve the dry and wet mechanical strength of polyester composites filled with silica, glass, silicate and metal oxides.
3. Improve the wet electrical properties of many inorganic mineral filled composite materials such as cross-linked ethylene and polyvinyl chloride.
4. It can be copolymerized with vinyl acetate and acrylate or methacrylate monomer to make a moisture-curable silylated polymer. These silylated polymers are widely used in coatings, adhesives and sealants to provide excellent adhesion and durability.

How to use: When silane coupling agent KH-570 is added to the resin, the amount added is 0.5-0.1%, depending on the type of resin. When used for pretreatment of inorganic fillers, the amount added is 0.5-0.1%, depending on the type of filler.
