Abstract
A composition for reclaiming paint and volatile organic paint carrier from industrial paint spray booths without increasing VOCs has been developed. The improvement over the existing booths recirculating hydrophilic based fluids, is the inclusion of a water based solution containing about 10 to about 45 per cent by weight of one or more N-alkyl pyrrolidones, about 15 to 40 percent by weight of one or more alkyl glycol mono alkyl ethers, a surfactant present in the amount of about 0.1 to 2.0 percent by weight, and the balance water.
