Q1: What is the primary function of BASF K6907/Pigment in polymer systems?
A: BASF K6907/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 improved dispersion stability and processing efficiency compared to dry pigments.
Q2: Is BASF K6907/Pigment suitable for food-contact applications?
A: BASF K6907/Pigment is formulated with components compliant with major global food-contact regulations for plastics, including FDA 21 CFR and EU Framework Regulation (EC) No 1935/2004. However, final regulatory compliance depends on the complete formulation, processing conditions, and end-use requirements — users must conduct their own verification per applicable jurisdiction and application.
Q3: How should BASF K6907/Pigment be incorporated into polymer melts?
A: It is typically introduced directly into the extruder feed throat or via side-stuffer during compounding, using standard gravimetric or volumetric dosing equipment. Good mixing design and sufficient residence time ensure optimal dispersion. Pre-drying is not required, but storage under recommended conditions (cool, dry, sealed) is essential to maintain rheological stability.
Q4: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and sources of heat or freezing. Avoid prolonged exposure to air to prevent surface skinning or viscosity changes. Stir gently before use if sedimentation occurs, as the product is designed for re-dispersibility without mechanical agitation.
