Bismuth vanadate pigments are used to obtain brilliantly colored lead-free stan­dard automotive finishes, automotive repair finishes and high-grade industrial paints. They are equally suitable for pigmenting solvent-based and solvent-free paints. They are ofparticular interest as a basis for brilliant, highly opaque orange, red and green shades, for which they are combined with organic pigments.

The chemistry of bismuth vanadate pigments makes them sensitive to acids. However, tests in which acids were applied to baking finishes under practical con­ditions have shown that the acid resistance of these pigments is normally compar­able to that of a highly stabilized lead chromate. The application of bismuth vana­date pigments in powder coatings and coil-coatings should be tested in customer material, because in such cases — more than in standard liquid paint systems — the suitability depends on the total formulation.
