Abstract: Disclosed are coating material compositions including (i) at least one polyol component (A), (ii) at least one crosslinking agent component (B) having groups reactive toward hydroxyl groups of component (A), (iii) at least one polyamide component (P1) in which the acid amide groups are connected by a saturated, aliphatic hydrocarbyl radical having 6 to 10 carbon atoms. Component (P1) is used in particulate form in which a size distribution (D50) is 20 to 100 μm. The coating material compositions further include (iv) at least one polycarboxamide component (P2) possessing the following structural formula in which s is 1, 2 or 3, t is 0 or 1, s+t is 2 or 3, R is a specific (s+t)-valent organic radical, and at least one of the radicals R1 and R2 carries at least one hydroxyl group. Also disclosed are methods of producing the coating material compositions.

Abstract: 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.

Abstract: The present disclosure relates to a primer coating material composition, obtainable by combining at least two components (A) and (B) of a coating material system, which are different from one another and present separately from one another, with component (B) being nonaqueous and including at least one polyisocyanate having more than two free isocyanate groups, at least one organic solvent, and, further, at least one Si-containing compound which contains at least one hydrolyzable radical and at least one non-hydrolyzable organic radical, for at least partial application to at least one optionally pretreated surface of a plastics substrate, to a method for producing a corresponding coating on such a substrate, and to a method for at least partially coating at least one surface of a plastics substrate with a multicoat paint system.
