Q1: What is BASF K4300/Pigment primarily used for?
A: BASF K4300/Pigment is a high-performance organic pigment dispersion designed for demanding industrial coating and plastic applications where excellent color strength, lightfastness, and thermal stability are required — particularly in automotive topcoats, industrial finishes, and engineering thermoplastics.
Q2: Is BASF K4300/Pigment compatible with water-based systems?
A: Yes, K4300/Pigment is formulated as a stable aqueous dispersion and is specifically engineered for compatibility with waterborne acrylic, polyurethane, and hybrid resin systems commonly used in architectural, industrial, and OEM coatings.
Q3: How should BASF K4300/Pigment be incorporated into a formulation?
A: It is typically added during the let-down or post-addition stage under moderate agitation. To preserve dispersion integrity and avoid shear-induced flocculation, avoid excessive high-shear mixing and ensure compatibility with other additives and resins is verified through small-scale trials.
Q4: Does BASF K4300/Pigment require stabilization against sedimentation during storage?
A: The product is supplied as a rheologically optimized dispersion with built-in anti-settling functionality. When stored under recommended conditions (cool, dry, frost-free), it maintains homogeneity over typical shelf life without requiring re-dispersion — though gentle stirring before use is advised if prolonged static storage occurs.
