Q1: What is the primary function of BASF K1070/WGP Pigment in polymer systems?
A: BASF K1070/WGP Pigment is a high-performance white pigment dispersion designed to provide excellent opacity, brightness, and uniform coloration in thermoplastic and thermoset polymers—particularly where high thermal stability and low volatility are required during processing.
Q2: Is BASF K1070/WGP Pigment suitable for food-contact applications?
A: This pigment dispersion is formulated for use in polyolefins, engineering plastics, and other polymer matrices where regulatory compliance is needed; however, suitability for food-contact applications depends on final formulation, processing conditions, and regional regulatory evaluation—users must conduct full compliance verification per applicable local requirements.
Q3: How should BASF K1070/WGP Pigment be incorporated into polymer melts?
A: It is typically introduced via masterbatch dilution or direct melt compounding using standard extrusion equipment. Good dispersion is achieved under moderate shear and temperatures compatible with the host polymer—pre-drying is generally not required, but moisture content should be monitored in hygroscopic systems.
Q4: Does BASF K1070/WGP Pigment offer resistance to UV degradation?
A: While the pigment itself exhibits inherent UV stability due to its inorganic composition, long-term weathering performance in end-use articles depends on synergistic effects with polymer matrix, stabilizers, and environmental exposure—complementary UV stabilizers are recommended for outdoor applications requiring extended durability.
Q5: What is the typical dosage range for BASF K1070/WGP Pigment in polymer formulations?
A: Dosage varies depending on desired opacity, polymer type, and processing method, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the base polymer—to achieve optimal performance without compromising mechanical properties.
