Abstract
The invention relates to coagulating agents formulated in the form of two separate components A and B for coagulating paints, waxes and coating compositions, which agents contain one or more aluminosilicate(s), one or more wax(es) and/or wax analogues and one or more active ingredient(s) and/or auxiliary material(s) that are known per se for coagulating and/or formulating, as well as to the aqueous slurries of the two-component agents and to the use thereof in circulation waters of paint disposal units.
Claims19
A two-component paint coagulant consisting of components A and B, wherein:
- component A consists essentially of:
- (A.a) from 50 to 100% by weight of at least one aluminosilicate,
- (A.b) from 0 to 30% by weight of at least one silicic acid, an alkali metal or alkaline earth metal salt thereof, or a mixture of at least one silicic acid with an alkali metal or alkaline earth metal salt thereof,
- (A.c) from 0 to 30% by weight of an alkaline earth metal salt,
- (A.d) from 0 to 20% by weight of a cyanamide, dicyandiamide, calcium cyanamide, or a mixture of one or more thereof,
- (A.e) from 0 to 10% by weight of a protonated or cationically modified polyethyleneimine,
- (A.f) from 0 to 10% by weight of emulsifiers/dispersing aids,
- (A.g) from 0 to 10% by weight of a component selected from the group consisting of amines and alkanolamines and mixtures thereof,
- (A.h) from 0 to 10% by weight of one of
- (A.h.1) a component selected from the group consisting of mixed formals, mixed ethers, and mixtures thereof, and
- (A.h.2) a component selected from the group consisting of phosphates and additional silicates, and, optionally,
- (A.i) antimicrobials and biocides, and, optionally,
- (A.j) acids to adjust pH, and, optionally,
- (A.k) corrosion inhibitors, and, optionally,
- (A.l) antifoam agents;
- and component B consists essentially of:
- (B.a) from 5 to 30% by weight of waxes, synthetic waxes, wax analogues, or mixture of two or more thereof,
- (B.b) from 70 to 95% by weight of water,
- (B.c) from 0 to 20% by weight of a cyanamide, dicyandiamide, calcium cyanamide, or mixture of two or more thereof,
- (B.d) from 0 to 10% by weight of a protonated or cationically modified polyethyleneimine,
- (B.e) from 0 to 10% by weight of emulsifiers/dispersing aids,
- (B.f) from 0 to 10% by weight of a component selected from the group consisting of amines and alkanolamines and mixtures thereof,
- (B.g) from 0 to 10% by weight of one or
- (B.g.1) a component selected from the group consisting of mixed formals, mixed ethers, and mixtures thereof, and
- (B.g.2) a component selected from the group consisting of phosphates and additional silicates, and, optionally,
- (B.h) antimicrobials and biocides, and, optionally,
- (B.i) acids to adjust pH, and, optionally,
- (B.j) corrosion inhibitors, and, optionally,
- (B.k) antifoam agents.
