ABSTRACT:
Aqueous solutions of R zirconium carbonate in which R is selected from ammonium and potassium have a carbonate: zirconium molar ratio not greater than 2.05 and can impart thixotropic properties to aqueous dispersions of polymers and copolymers, such as emulsion paint. The solutions may be prepared by reacting zirconium basic carbonate with ammonium or potassium carbonate solution and have a good storage stability, especially at high concentrations. They may be stabilized further by the addition of an acid selected from tartaric and gluconic acid.
