Beschreibung
Zusammenfassung:This invention relates to pigmented curable silicate compositions having better pigment dispersions as evidenced by improved color uniformity, hiding power, lower viscosity and consistency. The curable coating composition having improved pigment dispersion, consisting essentially of: (a) an aqueous phase of (i) from about 2 percent to about 50 percent of a watersoluble alkali metal silicate glass having a SiO2:M20 mole ratio of about 2:1 to about 4:1 wherein M represents the alkali metal; (ii) from about 0.01 percent to about 5 percent of a watersoluble base having a basicity greater than that of the silicate glass; and (iii) from about 50 percent to about 98 percent of water; (b) pigment, wherein the pigment represents from about 5 percent to about 90 percent by volume of the solids in the composition; and (c) a water-soluble latent insolubilizing agent for the silicate.
