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.

Compositions for treating paint spray booth water

Methods and compositions for treating paint spray booth water

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.

Cleaning and passivating treatment for metals

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.

Chromium-free aluminum treatment

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.

Reactive rinse aid for processing plastic surfaces

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.

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.
