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.

Nonaqueous coating material compositions, coatings produced therefrom and having improved adhesion and scratch resistance and also use thereof

The present invention relates to a radiation-curable coating composition, especially for producing a scratch-resistant coating on polycarbonate surfaces, comprising at least one urethane acrylate of an isocyanurate trimer of 1,6-hexamethylene diisocyanate and butanediol monoacrylate. The invention also relates to a method for producing scratch-resistant coatings on polycarbonate surfaces, to the use of the coating composition, and to a substrate coated accordingly.

Radiation-curable coating composition, method for producing scratch-resistant coatings, use of the coating composition, and substrate coated with a coating composition

The present invention relates to a nonaqueous coating material composition comprising The present invention further provides the coatings produced from these coating material compositions, and also the use of said coatings.

Coating material compositions and coatings produced therefrom, and use thereof

Binder mixture comprising a hydroxyl-containing compound (A), and at least 1.0% by weight, based on the nonvolatile constituents of the binder mixture, of a phosphorus- and nitrogen-containing catalyst (D) for the crosslinking of silane groups, wherein the hydroxyl-containing compound (A) comprises a hydroxyl-functional polyester having on average at least one hydroxyl function of the polyester esterified with a C8 to C9 monocarboxylic acid, and the catalyst (D) is blocked with at least one tertiary amine of the formula (I) where Ris an acyclic aliphatic or araliphatic hydrocarbon radical having at least 3 C atoms, Ris an acyclic aliphatic or araliphatic hydrocarbon radical which is the same or different from Rand/or R, and Ris hydrogen or an acyclic aliphatic or araliphatic hydrocarbon radical which is the same or different from Rand/or R.

Binding agent mixture, coating agents containing said binding agent mixture, and coatings produced from said coating agents, said coatings having a high scratch resistance, high weathering stability, and good optical properties
