Abstract
This specification covers zinc yellow (zinc chromate) pigments used in rust-inhibiting protective coatings and metal primers for ferrous and non-ferrous metals. The two types of pigments include: Type I and Type II. The pigment shall conform to the required composition for zinc, chromium, sulfates, chlorides, alkaline slats, matter insoluble in acetic acid, moisture and other volatile matter, and coarse particles. The following tests shall be conducted: chemical analysis, coarse particles, and mass color and tinting strength.
