specs:98% payment method: t/t in advance or l/c at sight appearance colorless or pale yellowish clear liquid boiling point 213-215 °c(lit.) flashing point 96℃ purity (%, m/m) 98.0 min. other physical properties packing packed with 5l、20l、200l plastic/steel drum or 1000l ibc container, also can be packed according to customer’s requirement. applications 3-mercaptopropyltrimethoxysilane (cas no. 4420-74-0), silane coupling agent kh-590, can improve the properties of the mineral-filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time may be achieved with kh-590. this silane chemically bonds reinforcing minerals such as silica, clay, mica and talc to the polymer matrix especially the sulfur-cured and metal oxide-cured rubber and elastomer. it can be used as a pretreatment on minerals or added at the time of compounding. mineral-reinforced rubbers such as rollers, wheels, white sidewalls, wire and cable insulation are the common case kh-590 could be used in. |
