  • Patent number: 7709555
    Abstract: Coating composition comprising one or more polythiols and one or more polyisocyanates and a latent base catalyst which is activatable by moisture, wherein the equivalence ratio NCO:SH is between 1:2 and 2:1. The latent catalyst is selected from the group of oxazolidine, aldimine, ketimine, and enamine. The latent catalyst is present in an amount of up to 20% relative to the weight of the curable material. The composition further comprises one or more photoinitiators in an amount of up to 4% relative to the weight of the curable material.
