Q1: What is the primary chemical nature of BASF C-K 0066K Pigment?
A: BASF C-K 0066K is an organic pigment dispersion formulated for high-performance applications. It is based on a chemically stable, high-chroma azo-type chromophore system, optimized for dispersion stability and compatibility with polar polymer matrices.
Q2: Is BASF C-K 0066K suitable for use in food-contact plastics?
A: This pigment is not pre-qualified for direct food-contact applications under global regulatory frameworks. Its suitability depends on final formulation, processing conditions, and end-use compliance requirements. Customers must conduct full regulatory assessment—including migration testing—when targeting food-contact applications.
Q3: What types of polymers is BASF C-K 0066K typically compatible with?
A: It demonstrates good compatibility with engineering thermoplastics such as polyamide (PA), polybutylene terephthalate (PBT), and polycarbonate (PC), especially in applications requiring heat stability and color consistency during melt processing.
Q4: How should BASF C-K 0066K be incorporated into a polymer system?
A: It is supplied as a ready-to-use liquid dispersion and is typically introduced via masterbatch dilution or direct compounding. For optimal dispersion, gentle mixing at moderate shear is recommended—avoid excessive thermal or mechanical stress that may destabilize the pigment particles.
Q5: Does BASF C-K 0066K require special handling or storage conditions?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and freezing conditions. Prolonged exposure to elevated temperatures or moisture may affect viscosity and dispersion integrity over time.
