PREPARATION OF REFINED PIGMENT FROM ELASTOMER

摘要

A pigment and method for making a pigment comprising a milled elastomer, wherein the milled elastomer has a D50 particle size of between about 5 and about 50 microns. A coating of the pigment has a smoothness of about 3 or less. The pigment is prepared by providing an elastomer; and milling the elastomer in the presence of milling media and solvent at a temperature from about 30° C. to about 70° C. The elastomer is insoluble in the solvent. The method for preparing the pigment from an elastomer comprises the steps of: providing an elastomer; and milling the elastomer in a media mill in the presence of milling media and solvent at a temperature from about 30° C. to about 70° C. The diameter of the milling media is from about 0.5 mm to about 10 mm, and the elastomer is insoluble in the solvent.
