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.

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.

Dual feed paint detackification program

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.
