Compositions comprising an isocyanate-functional compound, and isocyanate-reactive compound, and a co-catalyst

摘要

The invention pertains to a new composition comprising at least one isocyanate-functional compound comprising at least two isocyanate groups, at least one isocyanate-reactive compound comprising at least two isocyanate-reactive groups selected from mercapto groups, hydroxyl groups, and mixtures thereof, and a co-catalyst comprising a phosphine and a Michael acceptor. The invention further relates to a coating composition comprising the above composition, a method of coating a substrate comprising coating the substrate with the above composition, a substrate coated with that composition, the use of the above composition in the (re)finishing of large vehicles and refinishing of cars, and an adhesive comprising the above composition.
