Product Application of Stannous Octoate CAS#301-10-0
Stannous octoate is sensitive to hydrolysis and oxidation and should not be used in combination polyethers (premixes). Its catalytic activity is higher than that of dibutyltin dilaurate. It is widely used as a catalyst in polyurethane production, particularly for soft block polyether-type polyurethane foams, and is also suitable for polyurethane coatings, elastomers, and room-temperature curing silicone rubbers. As a divalent tin compound, it can be oxidized to a tetravalent tin form during foaming, remaining in the foam to act as an antioxidant without adversely affecting the foam’s performance.
