Q1: What is the primary function of BASF K2270/Pigment in polymer systems?
A: BASF K2270/Pigment is a high-performance organic pigment dispersion designed to provide strong, consistent coloration and excellent lightfastness in thermoplastic polymers, particularly polyolefins and engineering plastics. It functions as a ready-to-use liquid colorant offering good dispersibility and thermal stability during melt processing.
Q2: Is BASF K2270/Pigment suitable for food-contact applications?
A: While BASF K2270/Pigment is formulated with components commonly used in regulated polymer coloration, its suitability for food-contact applications depends on the final formulation, processing conditions, and regional regulatory requirements. Customers must conduct full compliance verification—including migration testing and regulatory dossier review—prior to use in food-contact articles.
Q3: How should BASF K2270/Pigment be incorporated into polymer melts?
A: It is typically introduced via gravimetric or volumetric dosing directly into the extruder feed throat or side feeder. Pre-blending with carrier resin is optional but not required. Good mixing efficiency and moderate shear conditions are recommended to ensure uniform dispersion without pigment degradation.
Q4: What storage conditions are recommended to maintain product stability?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and sources of heat. Avoid freezing, and ensure containers remain tightly closed to prevent solvent evaporation and skin formation.
