1. Name

γ-Mercaptopropyltriethoxysilane (domestic brand KH-580)

2. Technical indicators

Colorless and transparent liquid, density ρ200.987g/cm3, soluble in acetone, benzene, ethyl acetate, carbon tetrachloride, insoluble in water. Hydrolyzed in acid and alkaline solutions. Content: ≥97%

Density (ρ20)g/cm3: 0.987g/㎝3

Content: ≥97

3. Purpose

This product is mainly used as a coupling agent for EPDM rubber, styrene-butadiene rubber, natural rubber, chloroprene rubber, polysulfide rubber and chloroether rubber. It can produce good coupling between rubber and inorganic fillers such as silica. The combination can significantly improve the physical and mechanical properties (friction resistance) of the products, especially suitable for light-colored products. In coatings or electronic material sealants, it can improve the adhesion with precious metals.

4. Loading, storage and transportation

Packed in plastic barrels, net weight 20kg per barrel.

Store in a low-temperature, ventilated, dry room away from light and sealed, and is valid for one year.
