Formulation and application of alkaline zinc chloride compositions and detackification of paint spray booth wastes

摘要

Water used to wash the air in paint or lacquer spray booths in order to remove over-sprayed paint or lacquers is treated with a blend of a primary amino alcohol, a polyether polyamine and a water soluble salt of an amphoteric metal to reduce the tackiness of paint and lacquer solids and thereby reduce the tendency of over-sprayed paints and lacquers to adhere to walls, ceilings and floors of said spray booths and also to condition the paint and lacquer solids removed with the water so that they can be separated and the water recycled for further use in washing the air in the spray booth.
