This specification covers aluminum pigments in powder and paste forms for use in paints. The aluminum pigments are available in four types, as follows: Type I, leafing powder; Type II, leafing paste; Type III, nonleafing powder; and Type IV, nonleafing paste. Each type is grouped into three classes based on residue retained on a No. 325 sieve, as follows: Class A, fine; Class B, medium; and Class C, coarse. Materials shall be sampled, tested, and conform accordingly to composition of non-volatile matter, easily extracted fatty and oily matter (polishing lubricant), total impurities other than fatty and oily matter, coarse particles as total residue retained, and leafing ability.
