Abstract

The invention relates to a catalyst for the reaction between a compound that can react between isocyanate groups and an aliphatic diisocyanate with one isocyanate group bound to a primary carbon atom and one isocyanate group bound to a tertiary carbon atom. The catalyst is an ionogenic metal complex based on a metallic element from one of the groups III, IV or VII of the Periodic System, with at least one exchangeable counterion. Preferably the metallic element is titanium, zirconium, manganese or tin.
