Overview
Stannous Octoate is a tin(II) carboxylate catalyst widely used to promote crosslinking in polyurethane foam production and as a general polymerization catalyst. It's one of the most established tin(II) catalysts in the PU industry, valued for its balance of reactivity and handling characteristics.
Applications
- Crosslinking catalyst for rigid, semi-rigid, and flexible polyurethane foams
- General polymerization catalyst (esters, silicones)
- Ring-opening polymerization of lactides/glycolides (biodegradable polymer synthesis — PLA, PGS, PLGA)
- Room-temperature vulcanizing (RTV) silicone cure systems
Key Benefits
- Long-established, well-characterized catalytic performance in PU foam systems
- Effective gelation/crosslinking activity at low use levels
- Widely used in academic and industrial polymer synthesis (biomedical scaffolds, drug delivery polymers)
