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 method and composition for detackifying or coagulating and flocculating waterborne and mixed waterborne/solventborne paints in paint spray booth water. Aluminum chlorohydrate and a tannin containing polymer, preferably in an aqueous solution, are added to the paint spray booth water to detackify or coagulate and flocculate the paints.

Compositions and methods for detackifying paint spray booth water

Methods of treating circulating water containing oversprayed waterborne and/or solventborne paint, such as in a paint spray booth operation with copolymer of lignosulfonate and a cationic monomer subunit with Na.sub.2 CO.sub.3 and/or NaOH. The method does not require the use of metal salts or silicates.

Paint spray booth treatment program for waterborne and/or solventborne

Methods for detackifying paint spray booth water

In a paint spray booth wherein water is used to collect oversprayed paint, a process is disclosed for detackifying and coagulating oversprayed paint by the independent and concurrent addition of specific amounts of specific anions and cationic polymers to the water system.
