摘要： 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.
