Inorganic bismuth vanadate yellow pigments that are lead chromate-free
Lead and chromate are known for their hazards and efforts are made to eliminate them from various applications where they have been used on a large scale due to their availability and their high technical performances.
Inorganic yellow pigments containing lead chromates could be replaced by bismuth vanadate, in some applications. Bismuth vanadium tetra oxide (bismuth vanadate) colour code is Yellow 184 and it can be used to formulate mainly greenish yellows but also other shades. It provides good opacity and gloss and has good stability to weather conditions, heat and light. Its good dispensability makes it suitable for powder coatings. Bismuth vanadate can be used in different sectors and applications. The producer recommends it for high-performance industrial paints, architectural paints, coil coatings, powder coatings, automotive finishes (original equipment manufacturing and refinish) and plastics applications.
