Process for granulating lead chromate-containing pigments |
| abstract |
Abstract of the Disclosure A process is described for the production of high yields of lead chromate-containing pigments in a nondusting granular form. The process involves agitating in aqueous medium designated amounts of lead chromate-containing pigment, a friable, low molecular weight hydrocarbon-type resin softening at 50-95°C. and a cationic surfactant at a temperature above the softening point of the resin and continuing agitation at a temperature within the range of about 5 to about 20°C. above the softening point of the resin until the pigment dispersion is granulated. The process provides yields of at least 70% of granules in the particle size range of about 0.1 to about 4 millimeters. The granules are particularly useful as colorants for air-drying enamel coating systems and plastics. |
