Abstract: The present invention relates to a solventborne primer surfacer which comprises at least one additive preparable by reacting at least one alpha,omega-hydroxy-functionalized oligoester which possesses 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 primer surfacer. 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 additive identified above in solventborne primer surfacers for improving adhesion.

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.

Abstract: The present invention relates to a copolymer obtainable by copolymerization of at least three ethylenically unsaturated monomers each different from one another, the copolymer having at least three structural units (S1) and (S2) and (S3) different from one another, to the use of this copolymer as an adhesion-promoting additive in an aqueous coating composition, to an aqueous coating composition comprising at least one polymeric resin (A1), at least one pigment (B), and at least one copolymer of the invention, used as adhesion-promoting additive, as component (C), and also to methods for at least partly coating a substrate with a basecoat and for at least partly coating a substrate with a multicoat paint system.

Abstract: The present invention relates to a method for producing a multicoat paint system on a plastics substrate, in which a basecoat film or a plurality of directly successive basecoat films are produced on a plastics substrate, a clearcoat film is produced directly on the one basecoat film or on the topmost of the plurality of basecoat films, and subsequently the one or more basecoat films and the clearcoat film are jointly cured, this method being a method wherein at least one basecoat material used for the production of the basecoat films comprises at least one aqueous polyurethane-polyurea dispersion (PD) comprising polyurethane-polyurea particles, where the polyurethane-polyurea particles present in the dispersion (PD) comprise anionic groups and/or groups which can be converted into anionic groups, and have an average particle size of 40 to 2000 nm and also a gel fraction of at least 50%.
