ABSTRACT:
A process for detackifying paint, lacquer or enamel in a paint spray booth in which water is used to wash the air containing oversprayed paint, lacquer or enamel particles. The process comprises adding to the wash water a sufficient amount for the purpose of a cationic organic polymer and a selective anionic organic polymer. The process is particularly adaptable to activator catalyzed treatment programs in which the inorganic anion is lost as a precipitate due to adverse conditions such as increasing wash water acidity. The substitution of an organic anionic polymer for the inorganic anion alleviates this problem.
