ABSTRACT:
The process of this invention is directed to recovering diluted aqueous latex paint collected during cleaning of latex paint manufacturing equipment. The collected aqueous diluted latex paint is subjected to vacuum evaporation at temperatures between about 120.degree. F. and 170.degree. F. at reduced pressures of at least about 25 inches of mercury vacuum to produce a distillate containing above 99% by weight water and concentrated latex paint reusable as latex paint or as blend in latex paint products.
