    摘要: Polyisocyanate preparations containing latent tin catalysts are made from an organic polyisocyanate and a reaction product of a sulfonyl isocyanate and an organic tin catalyst in which at least one tin-oxygen bond is present. The organic tin catalyst preferably contains a tin-alkoxy, tin-siloxy, distannoxane and/or tin-carboxylate group. The reaction product of a sulfonyl isocyanate with a tin-carboxylate must generate carbon dioxide during its formation. The sulfonyl isocyanate and organic tin compound are used in quantities such that at least one isocyanato-sulfonyl group is present for each tin-oxygen bond. These polyisocyanate preparation are storage stable and may be used to produce adhesives, coatings and foams.

    摘要: Compositions which are storage stable at room temperature are made from an organic polyisocyanate, a compound containing at least two isocyanate-reactive groups and a latent catalyst. The latent catalyst is formed from an amine and an alkylating ester of an acid of phosphorus. These compositions react to form isocyanate polyaddition products when exposed to a temperature of 60.degree. C. or higher. These compositions are useful in the production of adhesives, foamed and non-foamed plastics and coatings.
