  • Publication number: 20080289968
    Abstract: A method of coating a substrate includes the steps of applying an electrocoat to the substrate, applying a powder primer onto the electrocoat, and then applying a topcoat onto the powder primer. The topcoat typically includes a powder basecoat and a clearcoat. The powder primer is applied to the electrocoat without first curing the electrocoat before application of the powder primer. The powder basecoat is applied to the powder primer without first curing the powder primer before application of the powder basecoat. The clearcoat is applied over the powder basecoat after which the electrocoat, the powder primer, the powder basecoat, and the clearcoat are simultaneously cured in an oven.

  • Publication number: 20080171145
    Abstract: A two-tone painting method includes applying a powder primer to a substrate, followed by a powder basecoat applied dry-on-dry onto the powder primer. The powder basecoat is preferably applied in the same painting booth as the powder primer, i.e., without curing the powder primer. The powder basecoat includes a flake additive, such as a mica flake or a metal flake, which prevents surface irregularities from forming in the powder primer and the powder basecoat as a result of not curing the powder primer before applying the powder basecoat. The substrate is then masked, and a second basecoat is applied. The masking is then removed and a clearcoat is applied. The second basecoat and the clearcoat are then cured simultaneously in an oven.

  • Patent number: 4483711
    Abstract: An improved aqueous electroless nickel plating bath and process for chemically depositing nickel on a substrate comprising an aqueous solution containing nickel ions, hypophosphite ions, a complexing agent, preferably a buffering agent and a wetting agent, and a small but effective amount of a sulfonium betaine compound sufficient to control the rate of nickel deposition and the concentration of phosphorus in the nickel deposit, preferably, in further combination with supplemental organic and/or inorganic rate stabilizers. The invention further contemplates a process for rejuvenating an electroless nickel bath which has been rendered inoperative due to the presence of excessive concentrations of supplemental stabilizing agents by the addition of a controlled effective amount of a sulfonium betaine compound sufficient to restore the bath to an operative plating condition.
