Q1: What is the primary application field for BASF K0961/ Pigment?
A: BASF K0961/ Pigment is primarily designed for use in high-performance industrial coatings, including automotive refinish, coil coating, and general metal finishing systems where excellent color strength, lightfastness, and thermal stability are required.
Q2: Is BASF K0961/ Pigment suitable for water-based formulations?
A: Yes, BASF K0961/ Pigment demonstrates good dispersibility and stability in both solvent-borne and water-based systems when processed with appropriate dispersants and milling techniques. Performance may vary depending on formulation pH, ionic strength, and rheology modifiers.
Q3: How does BASF K0961/ Pigment perform under elevated temperature conditions?
A: This pigment exhibits good thermal stability and retains its chromatic properties during typical curing cycles used in industrial baking applications, including those up to 200 °C for short durations. Long-term exposure above 220 °C may affect performance depending on binder system and atmosphere.
Q4: What is the recommended dosage range for optimal color development?
A: Dosage depends on the target shade depth, substrate, and film thickness, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to total formulation solids—to achieve strong, uniform coloration without compromising dispersion stability or film integrity.
