A method of electroetching a vertically oriented workpiece by moving a nozzle vertically with respect to the workpiece, the nozzle having a side proximate the workpiece being a cathode, comprising creating a moving cfiannel of electrolyte solution issuing from the nozzle and im- pinging directly against the workpiece; and damming the flow of the electrolyte solu- tion in a vertical direction. Process for Painting Polyvinyl Chloride U.S. Patent 5,536,532. July 16, 1996 R.E. Oaks, Canfield, Ohio A method of painting an article, includ- ing selecting a substrate having a polyvinyl chloride surface normally impervious to the adherence of a paint film; wetting the p01yvinyl chloride surface with a liquid lacquer retarder consisting essentially of toluene, n-butyl acetate, 2-butoxyethyl ac- etate, and 1-methoxy-2-propanol acetate in an amount to form a thin film under an applied pressure; allowing the liquid lac- quer retarder to react with the polyvinyl chloride surface; applying a paint film to the reacted surface of the polyvinyl chlo- ride surface; and allowing the paint film to dry while the residual of the liquid lacquer retarder vaporizes. Cathodic Electrocoat Compositions &S. Patent 5,536,776. July 16, 1996 C.W. Carpenter et al., assignors to BASF Corp., Southfield, Mich. A dispersant compound, comprising an acrylic backbone having a pigment-interac- tive substituent and a stabilizing substitu- ent, wherein the pigment-interactive sub- stituent has at least one primary amine group, and the stabilizing substituent com- prises an alkoxy-terminated polyalkylene oxide structure. Powder Coating Composition U.S. Patent 5,536,785. July 16, 1996 R.J. Foukes and C.A. Stants, assignors to BASF Corp., Southfield, Mich. A method of coating a substrate, com- prising spraying onto adjacent or overlap- ping areas a first thermosetting powder coating composition that is resistant to in- compatibility defects, comprising solid par- ticulates of a uniform mixture of a polyes- ter resin having an average of two or more carboxyl groups, a first crosslinker that is reactive toward the carboxyl groups of the polyester resin, 1-20% of a first acrylic copolymer having reactive functionality, METAL FINISHING • MARCH 1997
