Stannous octoate is prone to hydrolysis and oxidation, and it should not be combined with polyether premixes. Its catalytic activity surpasses that of dibutyltin dilaurate.
It is commonly used as a catalyst in the production of polyurethane, particularly for soft block polyether-type polyurethane foams, and also for polyurethane coatings, elastomers, and room temperature-curing silicone rubber. As a divalent tin compound, stannous octoate may oxidize to a tetravalent tin compound after foaming, which remains in the foam and acts as an antioxidant. This residual compound does not negatively impact the foam's performance.
