Q1: What is the primary function of BASF K1090/Pigment in polymer systems?
A: BASF K1090/Pigment is a high-performance organic pigment dispersion designed to provide strong, consistent coloration and excellent lightfastness in thermoplastic and thermoset polymers. It functions as a ready-to-use colorant with optimized wetting and stabilization for improved processing and dispersion stability.
Q2: Which polymer matrices is BASF K1090/Pigment typically compatible with?
A: This pigment dispersion shows good compatibility with a broad range of engineering plastics including polypropylene (PP), polyethylene (PE), polystyrene (PS), ABS, and certain polyamides (PA). Performance in polar or high-temperature resins should be verified through application testing due to formulation-specific interactions.
Q3: How is BASF K1090/Pigment supplied and what are key handling recommendations?
A: It is supplied as a viscous, paste-like dispersion in carrier resin, typically packaged in sealed metal pails or intermediate bulk containers (IBCs). Store in a cool, dry place away from direct sunlight; avoid freezing and prolonged exposure to elevated temperatures. Prior to use, gentle mechanical stirring is recommended to ensure homogeneity without introducing air.
Q4: Can BASF K1090/Pigment be used in food-contact or medical-grade applications?
A: BASF K1090/Pigment is not pre-qualified for food-contact or medical device applications. Its suitability for such uses depends on full regulatory assessment of the final formulation—including migration behavior, extractables profile, and compliance with applicable regional requirements. Customers must conduct their own due diligence and validation.
