摘要： A composition and method of treating paint spray booth water to detackify organic solvent based paint particles. The composition comprises a melamine polymer obtained from the reaction of melamine, aldehyde and an amine selected from the group consisting of dicyandiamide and glycine. These melamine polymers may be used in combination with a polyacrylamide, which combination exhibits surprising and unexpected effects when used to detackify organic solvent paint particles.

摘要： The present invention relates to a novel method for coagulating waterborne paints in paint spray booth recirculating water. The coagulant aid comprises a polynucleate hydroxy silicate-sulphate compound (hereinafter PASS) having the following average composition of the general formula:Al(OH).sub.B (SO.sub.4).sub.C (SiO.sub.X).sub.D (H.sub.2 O).sub.Ewherein B ranges from 0.75 to 2.0; C ranges from 0.30 to 1.12; D ranges from 0.005 to 0.1; X is greater than 2.0 but less or equal to 4.0 such that3=B+2C+2D(X-2)E is 1.5 to 4 when the product is in solid form; and E is larger than 4 when the product is in aqueous form, which may optionally be used together with alum or a mixture of alum and a polyamine. The coagulant aids of this invention may also be used advantageously with detackifying agents to simultaneously detackify and coagulate solvent based paint particles.
