Abstract: Methods and compositions for detackifying and dispersing, and coagulating/flocculating and dispersing solventborne and waterborne paints, respectively, in paint spray booth waters are disclosed. An aqueous composition of water soluble cationic polymer, nonionic surfactant and amphoteric surfactant is used in conjunction with a silicate compound to treat the paint spray booth waters.

Abstract: A cleaning and passivating treatment for metals comprising an amphoteric surfactant which is a caprylic acid derivative of imidazoline compounds. The treatment is substantially free of amines, alkanolamines and phosphates. The preferred treatment includes small quantities of borate ions and molybdate ions. In addition a nonionic surfactant may be added as a foam control agent.

Abstract: A method of forming a protective coating on aluminum and aluminum alloy surfaces to improve adherence of siccative coatings such as inks, paints, and lacquers. The method involves rinsing acid treatments from aluminum surfaces followed by coating the aluminum surfaces with a polymeric composition. The method provides improved adhesion of siccative coverings to treated aluminum surfaces over chrome containing and non-chrome containing fluoroacid and polymer mixture treatments.

Abstract: A method of enhancing the drainage of residual aqueous rinse from the external surfaces of plastic parts is disclosed. The method employs an aqueous solution of a tannin compound, which when applied to the surface of plastic parts will not rinse off during subsequent rinse stages and will remain on the plastic parts.

Abstract: Processes for enhancing the drainage of residual aqueous rinse from the external surfaces of plastic parts, such as auto fascia, are disclosed. The processes employ an aqueous solution of an amine functional silane compound, which when applied to the surfaces of plastic parts will not rinse off during subsequent rinse stages and will remain on the plastic parts.

Abstract: Processes for enhancing the drainage of residual aqueous rinse from the external surfaces of plastic parts, such as auto fascia, are disclosed. The processes employ an aqueous solution of a zircoaluminate compound, which when applied to the surfaces of plastic parts will not rinse off during subsequent rinse stages and will remain on the plastic parts.

Abstract: A process forming an organic coating, such as an autodeposited coating, on a plurality of small metallic articles by contacting the articles with a liquid coating composition containing an organic film-forming material comprising:(A) providing a plurality of said articles, with at least some of the articles being in contact with at least one other of said articles;(B) immersing the articles into a bath of said composition under conditions such that said articles are not in conttact with another article in said composition;(C) maintaining said articles in separated form in said composition for a period of time sufficiently long for the entirety of the surfaces of said articles to be coated with said composition; and(D) collecting the coated articles in the bath in a form in which at least some of the coated articles are in contact with another of said coated articles;wherein the coating composition is capable of forming on a steel panel immersed therein a coating having a wet strength such that its rinse resis
