  • Publication number: 20090317629
    Abstract: The present disclosure provides multicoat systems exhibiting ultraviolet (UV) stability after ultraviolet exposure and moisture exposure. The systems comprise at least one primer (G), at least one pigmented coating (P) disposed on a surface of the primer, and at least one ultraviolet (UV) absorber which has an absorption maximum of at least 370 nm. The pigmented coating (P) may be comprised of two or more coatings (P1), (P2) to (Pn). The multicoat systems may also comprise a transparent coating material (T) to form a transparent coating (K). The present multicoat systems demonstrate ultraviolet stability, reduced delamination of the pigmented coat from the primer and are available in a variety of shades for use in the finishing, refinishing and coating of component parts. The present disclosure also provides for a process for producing the multicoat system, and provides for the use of the system.

  • Patent number: 7579048
    Abstract: A process for improving the intercoat adhesion in a multicoat paint system utilizing a primer coat, an aqueous basecoat, and a clearcoat, where the multicoat paint system has been produced by means of a wet-on-wet technique. The clearcoat is produced using a pseudoplastic powder clearcoat slurry prepared by a secondary dispersion process or a melt emulsification process. The aqueous basecoat material used to produce the aqueous basecoat comprises a dispersed graft copolymer whose particles are composed of a hydrophobic core of copolymerized olefinically unsaturated monomers and of a hydrophilic shell which comprises a polyurethane, where said copolymer is prepared by free-radical (co)polymerization of the monomers in the presence of at least one polyurethane containing specially selected olefinically unsaturated groups.

  • Publication number: 20070106019
    Abstract: The invention relates to a method for producing chromophore and/or effect giving multilayer lacquers according to the wet-on-wet method. A water base lacquer is applied which contains at least one graft copolymer containing (A) at least one (meth)acrylate copolymer and (B) at least one polyurethane. The graft copolymer can be produced by (1) dispersing at least one hydrophilic or hydrophobic self cross-linking polyurethane (B) with a statistical average of at least one terminal and/or at least one lateral olefinically unsaturated group and at least one blocked isocyanate group per molecule in an aqueous medium. (2) A mixture of a at least one monomer (a1) with at least one isocyanate reactive functional group at last one monomer (a2) that can be copolymerised therewith is subsequently radically copolymerised in an emulsion in the presence of the polyurethane (B) or the polyurethanes (B). A powder slurry transparent lacquer layer is added to the resulting base lacquer layer.
