Abstract
Official abstract text for this publication.
Disclosed are combinations of one or more cationic starch(es) and aluminum salts to produce a composition for detackifying paint at lower doses than those required using conventional treatments while providing improved handling and a more “green” environmental profile. The compositions may be utilized in methods of detackifying and dispersing solvent borne paints and/or coagulating/flocculating and dispersing waterborne paints during the treatment of paint spray booth water.
First claim
Opening claim text (preview).
I claim: 1. A detackifying composition consisting essentially of: an acidic aqueous solution of a cationic starch; and a water soluble, inorganic metal salt selected from the group consisting of iron halogen salts, alum, aluminum chloride, and ferric sulfate. 2. The detackifying composition according to claim 1 , wherein: the composition comprises a solution in which the metal salt comprises from 50% to 85% of the dry weight and the cationic starch comprises from 15% to 50% of the dry weight.
