In the polyurethane sector, stannous octoate is the most extensively used tin catalyst. It can help to speed up the cross-linking reaction between polyether polyols and TDI, as well as balance the foaming and crosslinking reactions when combined with an amine catalyst, resulting in foamed plastic products with uniform pore permeability and good gas permeability. As a result, it is crucial in the production of polyurethane foam, particularly soft foam. In the polyurethane sector, it serves as an auxiliary agent, as well as a high-efficiency catalyst and antioxidant.
Besides being a lubricant, it can also be used as a curing agent and for several other purposes. The vulcanization of silicone rubber and the production of polyurethane use this catalyst. In addition, it’s also used to cure epoxy resins. Its catalytic activity is higher than that of dibutyltin dilaurate during curing.
