Abstract
A process for improving rheological properties and suspension properties of a nonaqueous fluid system containing finely divided solid particles, characterized in that an amide wax (I) having a melting point of about 100.degree. to about 160.degree.C. obtained from reaction of hydrogenated castor oil fatty acid or an organic acid mixture containing at least 30 molar per cent of hydrogenated castor oil fatty acid with amines and an emulsifiable polyethylene wax (II) having an acid number of about 2 to 50, a softening point of about 95.degree. to about 120.degree.C., a density of about 0.92 to about 0.98 and a penetration of about 1 to about 20 are added to the nonaqueous fluid system, and the nonaqueous fluid system obtained by aforesaid process.
