  • Patent number: 7625630
    Abstract: Disclosed is a combination effect coat that simultaneously provides at least one function selected from the group consisting of color, effect, or the combination thereof as well as at least one function selected from the group consisting of corrosion protection, adhesion promotion, absorption of mechanical energy, or the combination of two or more of the foregoing. The combination effect coat is produced by the application and curing of a pigmented powder slurry wherein the pigmented powder slurry is curable thermally, or curable thermally and with actinic radiation. The pigmented powder slurry consists of finely divided dimensionally stable constituents having an average particle size of from 0.8 to 40 ?m, has a residual volatile solvent content of less than 1% by weight, and comprises a (meth)acrylate copolymer having an epoxide equivalent weight of 400 to 2500; and a color pigment, an effect pigment, or a combination thereof.

  • Patent number: 7504134
    Abstract: Disclosed is a process for producing multicoat color and/or effect paint systems on automobile bodies. The disclosed process includes applying an aqueous base coat material to the body and drying or partially curing the resultant aqueous basecoat film, applying an aqueous powder slurry clearcoat material to the dried or partially cured aqueous basecoat film (I), and curing the films (I) and (II) by heat or by heat and actinic radiation (dual cure). Applying the aqueous powder slurry clearcoat material (II) involves electrostatic coating of the exterior body parts, followed by pneumatic spraying (compressed air spraying) of the interior body parts.
