Silane Coupling Agent Crosile 1891
Mercapto-functional silane used as a coupling agent in polysuflide and polyurethane caulks and sealants.
Useful in sulfur-cured and metal oxide-cured elasomers;
Useful in sulfur-cured and metal oxide-cured elasomers;
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;
