Main purpose:
As an efficient catalyst in the manufacture of polyurethane foam, coating, adhesive and sealant. Used as a hardening catalyst for dual layer polyurethane, polyester, nitro paint, ink and other coatings, as well as temperature air hardening coatings, with good oxidation resistance; Used as a catalyst and drying agent for the production of polyurethane plastics, polyurethane coatings, and silicone rubber;
Production method:
Made by dehydrochlorination reaction of dichlorodimethyltin and neodecanoic acid.
Impact on the environment:
The Occupational Safety Administration (OSHA) of the United States has environmental safety standards for the use of organotin in all industries [8H TWA (8-hour average) is 0.1mg/m (calculated as tin); short-term exposure value is 0.2 mg/m];
