| Résumé : |
This article deals with Bismuth vanadates' high performance yellow pigments and their applications.
Commercially available since the mid-1990s, Bismuth Vanadates(BV) pigments have been a huge success. They derive their dynamic power from their excellent properties in application and their competitive price to performance to ratio. Compared to P.Y. 83 and/or complex inorganic colour pigments (CICP) bismuth vanadates may be initially costlier but have been found to carry a significantly higher tinging strength and much cleaner shade. They dominate the bright yellow end of the colour spectrum and have shown to be a colour evaluators' first choice to replace leaded pigments, often at a 1:1 ratio in existing formulae.
Global demand for BV is estimated to be around 3000t/yr of which 90% is used in the coating industry (eg automotive, decorative, OEM and industrial). BV's use in powder coating and coil coating markets is increasing rapidly. To date, most of the developmental work has focused on bringing out BV with more specialised/customised properties for several applications to meet customer demands. For the longer term, R&D is concentrating on issues such as higher stability with heat and chemically aggressive resins.
Brufasol Yellow AL 2300, 30 and 40, produced by Bruchsaler Farbenfabrik GmbH & Co KG in Bruchsal, Germany, are brillant greenish to reddish yellow bismuth vanadates pigments. They exhibit good hiding power, tinting strength, temperature stability and the highest levels of weather resistance. Most importantly, BV's are environmentally-friendly alternatives to lead chromate pigments. |
