Abstract:
1. A paint or coating composition comprising: a binder, a liquid, and zirconium-containing aluminosilicate pigment particles comprising: at least a partial coating of a zirconium compound on the surface of alkali metal aluminosilicate particles and/or alkaline earth metal-modified alkali metal aluminosilicate particles, wherein the weight percentage of zirconium is in a range from about 0.05 to about 4 wt. %, based on the weight of the zirconium-containing aluminosilicate pigment particles; and wherein the zirconium-containing aluminosilicate pigment particles are characterized by: (i) an average particle size in a range from about 3 to about 7 μm; (ii) a BET surface area in a range from about 70 to about 200 m (iii) an oil absorption in a range from about 70 to about 120 cc/100 g; and (iv) a pH in a range from about 6 to about 7.8.
