1、 Product Name: hk171 silane coupling agent

2、 Chemical name: Vinyl trimethoxysilane

3、 Chemical structure formula CH2 = chsi (OCH3) 3

4、 Physical properties: colorless or light yellow transparent liquid, boiling point 123 ℃, specific gravity: (D25) 0.9650, refractive index (n25d) 1.391. Soluble in a variety of organic solvents, it can produce hydrolysis reaction, ester exchange reaction, halogenation reaction, reaction with metal organic matter, reaction with hydrocarbon acid and hydroxyester, reaction with alkali metal hydroxide, condensation reaction and redistribution reaction with other silanes, etc 。

5、 Usage: This product is an important organosilicon coupling agent. It can hydrolyze slowly when encountering water to form corresponding silanol with mild reaction. Because the product has the characteristics of stable treatment liquid and no corrosive gas overflow in the treatment process, the production and operation conditions are improved. It is often used as the surface treatment agent of glass fiber and the treatment agent of reinforced plastic products to improve the mechanical strength, heat and moisture resistance. This product can be copolymerized with a variety of monomers (such as ethylene, propylene, butene, etc.) or corresponding resin graft copolymerization to form a special purpose polymer material. This product is also a good adhesion promoter of silicone rubber and metal.

6、 Technical specifications:
