Stannous Octoate
Stannous octoate is a critical catalyst in the production of polyurethane (PU) materials, most notably in flexible foams. Its primary function is to accelerate the gelation reaction between polyols and isocyanates, ensuring efficient polymerization. This tin-based catalyst is highly valued for its ability to balance the exothermic gelation reaction with the blowing reaction, which is responsible for foam expansion. This balance is crucial for producing PU foams with uniform cell structure and desirable physical properties. Beyond flexible foams, stannous octoate also finds application in polyurethane elastomers, coatings, and even in the room-temperature vulcanization of silicone rubber and as a curing agent for epoxy resins. Its chemical properties include good solubility in common organic solvents and polyols, though it is sensitive to moisture and air, requiring careful storage to maintain its activity and prevent oxidation.
