Silane Coupling Agent HP 1891

CAS:14814-09-6 A-1891(Crompton)，Z-6910/6911(Dowcorning），Si-263(Degussa)，KH-580(China） HP-1891 is a kind of multifunctional silane coupling agent containing mercapto group. It act as activator, coupling agent, crosslinking agent and reinforcing agent. It has special effect as a herbicide of metal surface such as gold, silver and copper, it can improve corrosion resistance, antioxidation and improve it’s cohesiveness to polymer. 1. It is widely used in filled polymers such as nitrile, hydroxybenzene, aldehyde, epoxy, PVC, polystyrene, polyurethane, polysulfide rubber, NBR, EPDM and NR system. 2. It has special effect in tire industry and usually used for treating with silica and carbon black, fiberglass and talc powder inorganic fillers. It can markedly improve physical and mechanical proerties of vulcanizate. And it can improve tearing strength, tensile strength, abrasive resistance and reduce compression set of vulcanizates.
