  • Patent number: 8062761
    Abstract: This invention relates to a method for forming a multi-layer coating on a vehicle body, comprised of applying primer coating, base coating, and clear coat layers in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step. The primer layer comprises a film-forming binder comprising two acrylic polymers, the first being a caprolactone-modified branched acrylic polymer and the second being a caprolactone-modified linear acrylic polymer; and a crosslinking agent selected from aminoplast resin, blocked polyisocyanates, or mixtures thereof, wherein the composition is, essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both. The resulting multi-layered coating has excellent aesthetic appearance, strike-in resistance, chipping resistance, sag resistance, and film build even when formed in a three wet layered application method.

  • Patent number: 7740911
    Abstract: This invention relates to a method for forming a multi-layer coating, comprising sequentially applying a layer of primer coating composition, a layer of base coat composition, and a layer of clear coat composition on an automotive substrate in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step. The primer surfacer comprises a film forming binder, a volatile organic liquid carrier, and pigment(s); and the binder contains about (a) 40 to 95% by weight of a caprolactone-modified highly branched acrylic polymer having a hydroxyl and/or carboxyl monomer content, all or part of which has been reacted with caprolactone, of about 1 to 65% by weight and a weight average molecular weight of about 10,000 to 150,000; and (b) 5 to 60% by weight of an aminoplast resin crosslinking agent. The composition is essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both.

  • Publication number: 20090111938
    Abstract: The present invention provides for a primer-surfacer composition for use over sealed SMC parts such as automotive body panels that significantly reduces paint defects (such as paint pop and cracking defects) from appearing in the subsequently applied automotive topcoat finish. The coating composition includes silane and melamine components. The composition is sufficiently stable to be formulated as a one-pack coating composition.
