Application

Mercapto-functional silane Crosile®1891 used as a coupling agent in polysuflide and polyurethane caulks and sealants.

Useful in sulfur-cured and metal oxide-cured elasomers;

Crosile@1891 Can be either added at the time of compounding or used to pretreat minerals before hand.

Lower levels of this sulfur containing silane are used since it is efficient and fast

Chemically bonding reinforcing minerals like silica, clay, mica and talc to the polymer matrix;

Properties including modulus,tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time are improved in mineral-filled elastomers.
