This standard specifies specification requirements and test methods for zinc powder pigment for protective coatings. Zinc powder pigment is a grey fine powder mainly composed of metallic zinc in spherical granules. The standard covers performance indicators such as metallic zinc content, chemical purity, particle shape, Particle size distribution of zinc powder pigment, which affect its performance in coatings, such as dispersion, fineness of grinding, reactivity, conductivity and filling performance. In addition, the standard also provides relevant test methods to ensure that the pigment meets the expected performance requirements. By following this standard, enterprises that produce and use zinc powder pigment can ensure the mass and conformity of their products.
