decorative paints, and partly for powder coatings and coil-coating systems. In combination with additional pigments, B1VO4 can be used as a basis for important yellow, orange, red and green German standard colors RAL 1003, 1021, 1028, 2002, 3018, 6018, and 6029.
Thermostable bismuth vanadate pigments are available today with heat stability up to 300 °C. They exhibit very good fastness to light and weathering in plastics for outdoor use. The pigments have outstanding fastness to migration in plastics, and are easily dispersible. With their excellent heat stability, the thermostable types can be readily incorporated into polyolefins and ABS at 260-280 °C, and polyamide injection-molding materials at 280-300 °C.
