HD-112 Silane Coupling Agent (Z-6062, MTMO, A-189, KBM803, M8500 KH-590) Containing mercapto group, HD-112 silane coupling agent (A-189) has a special effect as an anti-rust agent for metal surface. When used to deal with the surfaces of gold, silver, copper and other metal, HD-112 can improve their decay resistance, anti-oxidation and adhesion with the polymer such as resins, etc. HD-112 has a good coupling effect on the vulcanized stuffing such as EPR (Ethylene Propylene Rubber), EPTR (Ethylene Propylene Terpolymer Rubber), SBR (Styrene Butadiene Rubber), NBR (Nitrile Butadiene Rubber) and so on, as well as significantly improves their physical and mechanical properties. Besides, HD-112 has a good effect as shrinkproof finishing agent on textile.
