The forthcoming expiration of authorisation for the use of lead pigments in 2022 means there is a need to find alternatives. Bismuth Vanadate Pigments (PY.184) are a perfect option because they retain an inorganic nature as well as providing the following properties:
Use in solvent and water-borne systems
High saturation and opacity, low oil absorption
Excellent weather fastness
Good alkali resistance, excellent in specific products
These are some of the products that DCL supplies to us and which we recommend at Comindex, including pigments that are suitable for paints, plastics, the automotive industry, etc.:
Yellow RMXS: This pigment has the highest colour strength of the Bismuth Vanadate Pigments on the market and at the same time is notable for its outstanding hiding power. Thanks to this, it provides the maximum value in use (cost savings due to using less pigment). It is easily dispersed and has excellent resistance properties (alkali and weather fastness). Its use is recommended for high quality finishes.
Yellow 3GMX: Its most distinctive feature is its outstanding ease of dispersion (almost stir-in) without losing maximum value in use. It also has high colour and gloss strength. It is particularly recommended for decorative and industrial paint.
Yellow 3GMXA: If you are looking for a pigment with high alkali resistance, then this is the product for you. It also has exceptional colour strength, hiding power and durability, which makes it perfect for high PVC systems and silicate coatings.
Yellow 2100: In addition to excellent hiding power, this Bismuth Vanadate Pigment has high resistance properties (thermal, chemical and weather fastness). It does not contain zinc, thus enabling it to obtain Ecolabel certification. It is recommended for high quality coatings.
Yellow 2GTS: This pigment is recommended for use in the plastics industry (above all for PA and highly engineered polymers) due to its high thermal (+320ºC), chemical and light resistance. It also has excellent colour strength and saturation.
