摘要
The combination of a diorganotin sulfide, -polysulfide, -dithiocyanate, bis(thiocyanato diorganotin) sulfide or bis(thiocyanato diorganotin) oxide with a tertiary amine functions as a latent catalyst for rigid polyurethane foams. Latency is not observed using a tertiary amine with other sulfur-containing organotin compounds.
