Q1: What is the primary application field for BASF B-K 5700K Pigment?
A: BASF B-K 5700K Pigment is a high-performance black pigment dispersion specifically developed for use in industrial coatings, including automotive refinish, coil coating, and general metal finishing systems where consistent jetness, excellent dispersion stability, and strong UV resistance are required.
Q2: Is B-K 5700K compatible with waterborne and solventborne systems?
A: Yes — B-K 5700K is formulated as a universal pigment preparation suitable for both waterborne and solventborne coating systems. Its optimized surfactant package ensures good compatibility across acrylic, polyester, epoxy, and polyurethane resin chemistries, though compatibility testing under specific formulation conditions is recommended prior to full-scale integration.
Q3: How should B-K 5700K be incorporated into a coating formulation?
A: It is typically added during the let-down or grinding stage using low-shear mixing to preserve dispersion integrity. Pre-dilution with a compatible carrier solvent or water may improve uniform distribution. Avoid high-shear processing post-addition, as it may destabilize the pigment structure and affect color development.
Q4: Does B-K 5700K offer enhanced weathering performance compared to standard carbon black pigments?
A: Yes — B-K 5700K is engineered to deliver improved resistance to chalking, fading, and gloss loss under prolonged UV exposure and cyclic humidity conditions, particularly in demanding exterior applications. This results from its controlled particle morphology and surface treatment designed to minimize photochemical degradation pathways.
