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

Compositions comprising (B1) at least one polyisocyanate-group-containing compound (B1) having free or blocked isocyanate groups and a cycloaliphatic polyisocyanate parent structure, and/or a polyisocyanate derived therefrom, and (B2) at least one polyisocyanate-group-containing compound (B2) having free or blocked isocyanate groups and an acyclic, aliphatic polyisocyanate parent structure, and/or a polyisocyanate derived therefrom, where at least one of component (B1) and component (B2) comprise at least one structural unit selected from the group of structural unit (I)&#x2014;NR&#x2014;(X&#x2014;SiR&#x2033;(OR')3-)&#x2003;&#x2003;(I),structural unit (II)&#x2014;N(X&#x2014;SiR&#x2033;(OR&#x2032;)3-)(X&#x2032;&#x2014;SiR&#x2033;(OR&#x2032;)3-)&#x2003;&#x2003;(II),and mixtures of two or more of the foregoing, wherein the compound (B1) is in an amount such that the binder fraction of the compound (B1) is between 5% and 45% by weight, based on the sum of the binder fraction of the compound (B1) and of the compound (B2), and the mixture of components (B1) and (B2) includes structural units (I) and structural units (II).

Coating agent compositions, coatings made therefrom and exhibiting high scratch resistance and good polishability, and use thereof

Disclosed are coating compositions comprising film-forming material with at least one reactive functional group G'&#x2033;, catalyst for the crosslinking of the silane groups, aprotic solvents, and at least one adduct with silane functionality which is prepared by an addition reaction of Also disclosed are multicoat paint systems in which the transparent coating has been produced from these coating compositions, methods of making and use, as well as methods of improving the hardness and/or the scratch resistance of coatings.

Coating agent containing addition compounds with silane functionality, and highly scratch-resistant coatings with improved crack resistance

Disclosed are coating compositions comprising (a) at least one hydroxyl-containing compound (A), (b) at least one compound (B) having isocyanate groups, and (c) at least one catalyst (D) for the crosslinking of silane groups, said catalyst (D) comprising phosphorus. It is an aspect of the disclosed coating compositions that (i) one or more constituents of the coating composition contain hydrolyzable silane groups and (ii) the coating composition can be finally cured to a coating which has statistically distributed regions of an Si&#x2014;O&#x2014;Si network.

Coating agents having high scratch resistance and weathering stability

The invention relates to coating agents, containing (A) at least 50 wt. %, (in relation to the content of non-volatile substances in said coating agent), of at least one compound (A1) and/or (A1') comprising at least two reactive groups of formula (I): &#x2014;X&#x2014;SiR&#x2033;x(OR&#x2032;)3-x, in which R&#x2032;=hydrogen, alkyl or cycloalkyl, whereby the carbon chain can be interrupted by non-adjacent oxygen, sulphur or NRa groups, Ra=alkyl, cycloalkyl, aryl or aralkyl, X=a linear and/or branched alkene or cycloalkene group comprising between 2 and 20 carbon atoms, R&#x2033;=alkyl, cycloalkyl, aryl or aralkyl, whereby the carbon chain can be interrupted by non-adjacent oxygen, sulphur or NRa groups, and x=0 to 2, (B) a catalyst for cross-linking the &#x2014;Si(OR&#x2032;)3-x units, and (C) an organic solvent or a mixture of organic solvents.
