Abstract
A method for detackifying oversprayed paint solids in a paint spray booth utilizes an oil-in-water emulsion as the hydrophilic fluid for capturing and detackifying oversprayed paint, which emulsion contains a certain nonionic surfactant, which surfactant greatly improves detackification performance when the paint formulation being sprayed is a low VOC formulation, and particularly a two-component formulation. The nonionic surfactant is an ethoxylated C.sub.8-10 alkyl phenol having an HLB value of from about 4.5 to 15.5.
