Abstract
This invention relates to a process for detackifying and dispersing paint solids for example obtained from paint overspray in enclosed areas such as paint spray booths. The process includes contacting an oil-in-water emulsion with an aqueous solution whereby the oil-in-water emulsion is destabilised. On subsequent contact of paint particles with the aqueous solution comprising the destabilised oil-in-water emulsion, the paint is adsorbed on to destabilised emulsion particles. The process provides an effective method of denaturing paint over-spray which is easily handleable and effective over a wide range of paint compositions. In one embodiment of the invention, the oil-in-water emulsion comprises a latex.
