Fluorine-Containing Nonaqueous Coating Material Composition, Coating Methods, And The Use Of The Coating Material Composition

摘要

The present invention provides nonaqueous coating material compositions comprising 30% to 80% by weight of at least one poly(meth)acrylate (A), 20% to 70% by weight of one or more polyisocyanate group-containing compounds (B), and one or more catalysts (D), the weight percentages being based in each case on the binder content of (A) and (B), respectively, and the sum of the weight fractions of (A) plus (B) being in each case 100% by weight,;wherein the poly(meth)acrylates (A) comprise 0.05% to 15.0% by weight of one more fluorine-containing reaction products of one or more diisocyanates (PI) having two isocyanate groups with different reactivities, one or more (per)fluoroalkyl monoalcohol components (FA), and optionally one or more compounds (V) having at least one group (G1) that is reactive toward isocyanate groups, and optionally having a further functional group (G2), which is different from group (G1).

1. A nonaqueous coating material composition comprising:
(A) 30% to 80% by weight of a polyhydroxyl and (per)fluoroalkyl group-containing (meth)acrylate component (A), (B) 20% to 70% by weight of one or more polyisocyanate group-containing compounds (B), and (D) one or more catalysts (D), the weight percentages of components (A) and (B) being based in each case on the binder content of components (A) and (B), respectively, and the sum of the weight fractions of components (A) plus (B) being in each case 100% by weight, wherein the poly(meth)acrylate component (A) comprises as a synthesis component 0.05% to 15.0% by weight, based in each case on the amount of all of the compounds used in preparing the poly(meth)acrylate component (A), of one or more perfluoroalkyl group-containing reaction products (U) of: (i) one or more diisocyanates (PI) having two isocyanate groups with different reactivities, (ii) one or more (per)fluoroalkyl monoalcohol components (FA), and (iii) optionally one or more compounds (V) having at least one group (G1) that is reactive toward isocyanate groups, and optionally having a further functional group (G2), which is different from group (G1).
