Latent catalysts for the isocyanate polyaddition reaction

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 DEG C. or higher. These compositions are useful in the production of adhesives, foamed and non-foamed plastics and coatings.
