Q1: What is the primary application field for Viscofil Black 2BLN?
A: Viscofil Black 2BLN is specially designed for use in high-viscosity, solvent-free or low-solvent industrial coatings and printing inks—particularly where excellent jetness, dispersion stability, and rheological compatibility are required.
Q2: How does Viscofil Black 2BLN differ from conventional carbon black pigments?
A: Unlike standard carbon blacks, Viscofil Black 2BLN features a tailored surface treatment that enhances wetting and deagglomeration in demanding resin systems—especially epoxy, polyurethane, and acrylic binders—reducing milling time and improving gloss retention and color consistency.
Q3: Is Viscofil Black 2BLN suitable for food-contact coatings?
A: This pigment is not pre-qualified for direct food-contact applications. Its suitability depends on full formulation assessment, including final regulatory review by the responsible authority and compliance with applicable regional requirements for coated substrates.
Q4: What is the recommended dosage range in typical coating formulations?
A: Dosage is formulation-dependent, but Viscofil Black 2BLN is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to achieve deep black shades while maintaining viscosity control and film integrity.
Q5: Can Viscofil Black 2BLN be used in water-based systems?
A: While primarily optimized for solvent-borne and 100% solids systems, successful incorporation into water-based dispersions is possible with appropriate dispersants and process adaptation—however, performance must be verified case-by-case through lab-scale testing.
