Q1: What is the primary application field for BASF BR-K 3890K Pigment?
A: BASF BR-K 3890K Pigment is specifically developed for use in high-performance industrial coatings, including automotive refinish and OEM coating systems, where excellent color strength, weather resistance, and thermal stability are required.
Q2: Is BR-K 3890K suitable for water-based coating formulations?
A: Yes, BR-K 3890K is engineered for compatibility with both solvent-borne and aqueous systems. Its surface treatment facilitates good dispersion stability and rheological behavior in water-based industrial coatings without requiring extensive reformulation.
Q3: How should BR-K 3890K be dispersed to achieve optimal performance?
A: Optimal dispersion is typically achieved using high-shear mixing or bead milling. Pre-wetting with compatible solvents or dispersing agents is recommended to ensure full deagglomeration and maximize color development and gloss retention.
Q4: Does BR-K 3890K offer good UV resistance and long-term color stability?
A: Yes, BR-K 3890K exhibits inherently high photostability due to its chemically robust molecular structure and optimized particle morphology, making it well-suited for exterior applications demanding sustained color fidelity under prolonged UV exposure.
Q5: What is the typical dosage range when using BR-K 3890K in coating systems?
A: Dosage depends on the desired opacity, color intensity, and formulation matrix, but BR-K 3890K is generally used at low concentrations—typically ranging from 0.1% to 2% by weight in the final coating—thanks to its high tinting strength and efficient light absorption.
