Coating compositions and coatings with improved soiling resistance and (self-)cleaning properties are disclosed. The coating compositions and coatings may be nonaqueous coating compositions and may include at least one hydroxyl group-containing compound, at least one isocyanate group-containing compound having free or blocked isocyanate and silane groups, at least one catalyst for the crosslinking of the silane groups, and at least one alkoxysilyl-functional siloxane.

Coating compositions and coatings produced therefrom with improved soiling resistance and (self-)cleaning properties and use thereof

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 solventborne clearcoat material which comprises at least one additive preparable by reacting at least one alpha,omega-hydroxy-functionalized oligoester which has an OH number of 30 to 160 mg KOH/g, a theoretical carbon-carbon double bond content of 1 to 2.5 mmol/g, a number-average molecular weight of 1000 to 3000 g/mol, and a weight-average molecular weight of 2800 to 10 000 g/mol, and at least one alkoxysilane which possesses an OH-reactive functional group, the sum of the weight percentage fractions of all additives of the invention being 0.5 to 10 wt %, based on the total amount of the solventborne clearcoat material. The present invention further relates to a process for producing multicoat paint systems, and to multicoat paint systems producible by means of said process. The invention further relates to the use of the above-identified additive in solventborne clearcoat materials for the purpose of improving adhesion.

Adhesion promoter for solventborne clearcoat materials

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

Described is a clearcoat coating composition, its use, and a process for preparing the clearcoat coating composition. The clearcoat coating composition comprises (A) at least one polyester having an OH number of 80-250 mg KOH/g; (B) at least one butanol-etherified melamine-formaldehyde resin having a crosslinking onset temperature between 65&#xb0; C.-100&#xb0; C. lower than the crosslinking onset temperature of hexamethoxy-methylmelamine; (C) at least one butanol-etherified melamine-formaldehyde resin having a crosslinking onset temperature between 30&#xb0; C.-60&#xb0; C. lower than the crosslinking onset temperature of hexamethoxymethylmelamine; (D) at least one organic urea compound as rheological assistant; and (E) at least one acid catalyst.

Clearcoat coating composition, method for production and use

The invention relates to coating compositions based on organic solvents and comprising at least one hydroxyl-containing compound (A), at least one crosslinking agent (B) having groups reactive toward hydroxyl groups, and at least one silica gel based matting agent (M), wherein The present invention further provides multistage coating methods using these coating compositions, and also the use of the coating compositions as clearcoat or application of the coating method for automotive OEM finishing, for the finishing of parts for installation in or on automobiles, and for automotive refinishing.
