Series 11 of OCCA Weekly Webinars continues with "Bismuth Vanadate as a very viable alternative to lead chrome pigments" presented by Dr Markus Richter and Dr Tomislav Argirevic of Bruchsaler Farbenfabrik. The webinar will take place via Zoom on Wednesday 13 December at 2:30pm.
The alternative to lead chromate pigments are bismuth vanadate pigments and its blending versions which contain in addition organic pigments. Brilliant yellow bismuth vanadate pigments ranging from greenish to reddish shades have high opacity and excellent weather fastness. Our BRUFASOL AL ® product line offers pure bismuth vanadate pigments with high stability in different chemical environments. They are particularly suitable for applications like industrial and powder coatings and are applied in plastic materials like HDPE, ABS and PVC.
With our BRUFABLEND ® pigment line we are able to replace all types of lead chromate color shades which can not be replaced by bismuth vanadate pigments alone. These mixtures of bismuth vanadate and organic pigments can replace all countertypes on the market. In this presentation we will offer good arguments to replace lead chromate pigments not only from ecotoxicological point-of-view but also from the aspect of pigment properties like environmental stability, coloristic features and applicability in different systems.
