Abstract

See full text

The present invention relates to novel modified polyisocyanurate plastics obtainable by catalytic trimerization of a composition A), wherein the composition A) comprises oligomeric modified polyisocyanates B) that are a reaction product of an oligomeric polyisocyanate B1) and at least one functionalizing reagent B2) reactive toward isocyanate groups, where the composition A) has a content of monomeric diisocyanates of not more than 20% by weight and where the at least one functionalizing reagent B2) reactive toward isocyanate groups has at least one functional group reactive toward isocyanate groups which is not an isocyanate group. The invention further relates to the process from which the polyisocyanurate plastics of the invention are obtainable, to the use of the polyisocyanurate plastics of the invention for production of coatings, films, semifinished products, composites and moldings, and to substrates coated with such a coating.
