摘要
Provided is an agent for treating water circulating through a wet paint booth, the agent being capable of reducing the adhesion of a solvent-based paint and coagulating a solvent-based paint to a sufficient degree regardless of the type of the paint, the type of the curing agent used, or the facility conditions, the agent also being capable of markedly reducing the foaming of a water-based paint, even when being used in a small amount. An agent for treating water circulating through a wet paint booth includes a phenolic resin having a weight-average molecular weight of more than 3,000 and 100,000 or less, the phenolic resin serving as an active component. A method for treating circulating water circulating through a wet paint booth includes coagulating a water-based paint and/or a solvent-based paint included in the circulating water by adding the agent to the circulating water.
