Q1: What is the primary chemical class and typical application field for BASF 5B-K 4535K Pigment?
A: BASF 5B-K 4535K is a high-performance organic pigment dispersion, formulated for demanding industrial applications including automotive coatings, industrial finishes, and high-gloss decorative paints. It is not a dye or solvent-soluble colorant, but rather a stabilized pigment preparation designed for excellent lightfastness, weather resistance, and compatibility with common resin systems.
Q2: Is BASF 5B-K 4535K suitable for use in food-contact or pharmaceutical applications?
A: No — BASF 5B-K 4535K is not approved for direct food-contact, pharmaceutical, or cosmetic applications. It is intended exclusively for industrial coating and paint systems where regulatory compliance follows applicable industrial safety and environmental guidelines. Customers requiring food-grade pigments must consult BASF’s dedicated portfolio of certified products.
Q3: How should BASF 5B-K 4535K be incorporated into a coating formulation?
A: The pigment is supplied as a ready-to-use liquid dispersion and is typically added during the let-down or grinding stage of coating production. It exhibits good compatibility with acrylic, polyester, alkyd, and polyurethane binder systems. For optimal performance, avoid excessive high-shear mixing after addition and ensure thorough but gentle homogenization to preserve dispersion stability.
Q4: What are the recommended storage conditions for long-term stability?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and frost. Prolonged exposure to freezing temperatures may cause irreversible aggregation, while extended storage above 35 °C may reduce shelf life. Under proper conditions, the product typically maintains its performance characteristics for up to 12 months from the date of manufacture.
