Patclin Chemical Co. Inc. Yonkers, N. Y

Patclin Chemical will highlight new advancements that the company has made in brass and copper alloy bright dip. Patclin #926 Pat Brite is a new process for producing an ultrabrilliant finish on copper and brass. The Patclin #926 produces a surface that is active and suitable for plating, oxidizing, or soldering; will readily accept lacquer finishes where the true brass or copper color is desired, and is superior to those produced in the conventional nitric-sulfuric or chromic-acid-based baths. Patclin will also feature other innovations that the company has made in both the metal and paint stripping fields and will present a noncyanide alkaline stripping process that was specifically developed to remove nickel plate from steel, copper alloys, and copper by immersion.
