Abstract
The invention relates to novel modified polyisocyanurate plastics, obtainable by means of catalytic trimerization of a composition (A), wherein the composition (A) contains oligomeric, modified polyisocyanates (B), which represent a reaction product from an oligomeric polyisocyanate (B1) and at least one functionalization reagent (B2) which is reactive to isocyanate groups, wherein the composition (A) comprises a content of monomeric diisocyanates of 20 wt % at maximum and wherein the at least one functionalization reagent (B2) which is reactive to isocyanate groups has at least one relative functional group which is reactive to isocyanate groups and which is not an isocyanate group. The invention further relates to the method by which the polyisocyanurate plastics according to the invention are obtainable, to the use of the polyisocyanurate plastics according to the invention for producing coatings, films, semi-finished products, composite materials and molded parts, and substrates coated by such a coating.
