Q1: What is the primary application field for BASF K4270/ 4BP Pigment?
A: BASF K4270/ 4BP Pigment is specifically engineered for use in high-performance industrial coatings, including automotive refinish, coil coating, and durable plastic applications where excellent lightfastness, thermal stability, and dispersion consistency are required.
Q2: Is this pigment suitable for water-based systems?
A: Yes — BASF K4270/ 4BP Pigment is formulated to deliver robust performance in both solvent-borne and water-based coating systems, with good compatibility in acrylic, polyester, and polyurethane dispersions when properly dispersed using recommended wetting agents and dispersing equipment.
Q3: How should this pigment be incorporated into a formulation?
A: It is recommended to incorporate BASF K4270/ 4BP Pigment via high-shear dispersion techniques (e.g., bead milling or high-speed dissolvers) after pre-wetting with compatible solvents or resins. Optimal dispersion ensures maximum color strength, gloss, and stability across the final system.
Q4: Does this pigment contain heavy metals or halogens?
A: BASF K4270/ 4BP Pigment is manufactured without intentionally added heavy metals (e.g., lead, cadmium, mercury, or hexavalent chromium) and is free from brominated or chlorinated aromatic compounds, aligning with global sustainability and regulatory expectations for industrial pigments.
Q5: What is the typical dosage range in coating formulations?
A: Dosage depends on the desired color strength, opacity, and substrate requirements, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in the total formulation — with optimal levels determined through lab-scale trials and rheological evaluation.
