Q1: What is BASF K3911HD/Pigment primarily used for?
A: BASF K3911HD/Pigment is a high-performance organic pigment dispersion designed for demanding industrial coating and ink applications, particularly where excellent color strength, lightfastness, and thermal stability are required — such as in automotive refinish, industrial maintenance coatings, and packaging inks.
Q2: Is BASF K3911HD/Pigment compatible with water-based and solvent-based systems?
A: Yes, K3911HD/Pigment is formulated to offer broad compatibility across both aqueous and organic solvent-based media. Its stabilized dispersion technology supports stable integration into acrylic, polyester, alkyd, and polyurethane resin systems, though optimal performance may require minor adjustment of rheology or wetting agents depending on the base formulation.
Q3: How should BASF K3911HD/Pigment be incorporated into a formulation?
A: It is recommended to add K3911HD/Pigment during the let-down or post-addition stage under moderate shear to avoid deagglomeration issues. Pre-dilution with a compatible carrier solvent or resin solution may improve dispersion uniformity. Final dosage typically depends on target color strength and opacity requirements, generally ranging from 0.1% to 2% by weight relative to total formulation solids.
Q4: Does BASF K3911HD/Pigment meet regulatory requirements for food-contact applications?
A: BASF K3911HD/Pigment is not intended for direct food-contact applications unless explicitly validated and approved within a specific end-use system. Formulators must conduct full regulatory assessment — including migration testing and compliance verification — based on final cured film composition, substrate, and intended use conditions.
