A method for the treatment of the circulating water collecting surplus paint in a wet spray booth, which method is characterized by the addition of melamine-aldehyde acid colloid solution.
A water circulating system for treating surplus paint in a wet spray booth comprising, a circulating water and melamine-aldehyde acid colloid solution prepared by adding 1.0 to 2.5 mols of aldehyde into 1 mol of melamine for reaction therebetween and adding thereinto 0.5 to 5 mols of an acid relative to 1 mol of melamine, said colloid solution being added into the circulating water in an amount of 0.1 to 300 parts by weight relative to one part by weight of surplus paint to be treated, said water circulating system having a pH in the range of 4 to 10.
A wet spray booth treating agent comprising melamine-aldehyde acid colloid solution, an alkali agent for diminishing tackiness of a paint and corrosion-proofing of a circulating system, a surface active agent for improving paint dispersibility and emulsifiability, and a flocculant for improving solid-liquid separating property.
