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

Disclosed herein is a coating material compositions containing (A) a polyhydroxyl group-containing component, (B) a component (B) having on average at least one isocyanate group and having on average at least one of: at least one hydrolyzable silane group of the formula (I): &#x2014;NR&#x2014;(X&#x2014;SiR&#x2033;x(OR')3-x), and at least one hydrolyzable silane group of the formula (II): &#x2014;N(X&#x2014;SiR&#x2033;x(OR&#x2032;)3-x)n(X&#x2032;&#x2014;SiR&#x2033;y(OR&#x2032;)3-y)m, (D) a phosphorus and nitrogencontaining catalyst, and a catalyst (Z), wherein: the catalyst (Z) is selected from zinc and bismuth carboxylates, of aluminum, zirconium, titanium and/or boron chelates and/or of inorganic, tin-containing catalysts, and mixtures thereof; and the coating material composition comprises at least one reaction accelerator (R) which is selected from the group of inorganic acids and/or of organic acids and/or of partial esters of the inorganic acids and/or of partial esters of the organic acids. Processes for producing multicoat paint systems, and coatings obtained from the coating material compositions are also disclosed.

Polyurethane coating material compositions and use thereof for producing multicoat paint systems

The present invention provides nonaqueous coating material compositions, multistage coating processes and also the use of the coating material compositions, comprising

Coating material compositions and coatings produced therefrom combining high scratch resistance and good polishability and good optical properties, and use thereof

The present invention relates to a multicoat effect and/or color paint system, a method for producing the multicoat paint system, and also the use thereof. The transparent coating material composition comprises at least one rheological assistant (R) based on fumed silica and comprises a polyisocyanate group-containing component (B) which additionally has at least one structural unit of the formula (I) and/or at least one structural unit of the formula (II).

Multicoat effect and/or color paint system and method for producing it, and its use

A process is disclosed for producing moldings, in which a pigmented coating composition (P) and a free-radically crosslinkable coating composition (K), which after crosslinking to completion produces a transparent coating (KE) are applied to a support sheet, wherein a dried but as yet not completely crosslinked coating (KT) is produced from the coating composition (K), the coated support sheet is shaped and is injection backmolded or foam-backed, and the coating (KT) is cured or aftercured; the crosslinkable coating composition (K) comprising a free-radically crosslinkable component (KK) which contains hydrogen bond forming structural elements.

Method for producing molded parts, especially for use in automobile manufacture, and corresponding appropriate films comprising a coating

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 herein is a refinish sheet produced by (1) coating one side of a temporary carrier sheet (A) with at least one aqueous coating material (B) comprising at least one free-radically crosslinkable binder (B1) having a glass transition temperature of &#x2212;70 to +50&#xb0; C., an olefinically unsaturated double bond content of 2 to 10 eq/kg, and an acid group content of 0.05 to 15 eq/kg to produce at least one resultant layer (B); and (2) drying but not curing, or only part-curing, the at least one resultant layer (B) to produce at least one dried, uncured or part-cured layer (B). Also disclosed is a method of repairing a surface of a coated substrate using the refinish sheet.

Repair film and use thereof

A process for producing moldings, in which a solventborne or aqueous, pigmented coating composition (P) and a free-radically crosslinkable coating composition (K), which after crosslinking to completion produces a transparent coating (KE) are applied to a support sheet, a dried but as yet not completely crosslinked coating (KT) is produced from the coating composition (K), the coated support sheet is shaped and is injection backmolded or foam-backed with a liquid polymeric material, and the coating (KT)&#x2014;if this has not already taken place&#x2014;is cured or aftercured; the crosslinkable coating composition (K) comprising a free- radically crosslinkable component (KK) which comprises carbamate and/or biuret and/or allophanate and/or urea and/or amide groups.
