Abstract: A nonaqueous coating material composition and a coating produced from the coating material composition are provided. The coating material composition contains at least one polyhydroxyl group-containing component, at least one polyisocyanate group-containing component, at least one catalyst, and at least one urethane additive (PF) which has specific groups. The urethane additive (PF) is prepared by reacting 0.5 to 20 mol % of the isocyanate groups originally present in a polyisocyanate (PI) with a component (Ia) and 10 to 99.5 mol % of the isocyanate groups originally present in the polyisocyanate (PI) with a component (IIa). The component (Ia) contains at least one perfluoroalkyl group of a specific formula and one group reactive toward the isocyanate groups. The component (IIa) contains at least one silane group of a specific formula and one group reactive toward the isocyanate groups.
