Q1: What is the primary chemical nature and classification of BASF 3G-K Pigment?
A: BASF 3G-K Pigment is an organic pigment based on a high-performance azo condensation structure, engineered for excellent lightfastness, thermal stability, and dispersion characteristics in polymer matrices.
Q2: In which polymer systems is BASF 3G-K Pigment most commonly processed?
A: It demonstrates strong compatibility and stability in polyolefins (e.g., PP and PE), engineering thermoplastics such as ABS and PS, and certain PVC formulations—particularly where heat resistance up to 280 °C is required during processing.
Q3: How should BASF 3G-K Pigment be dispersed for optimal color development and performance?
A: For best results, it is recommended to use high-shear compounding or masterbatch preparation with suitable carrier resins. Pre-wetting and controlled temperature profiles during melt processing help achieve uniform dispersion and minimize agglomeration.
Q4: Is BASF 3G-K Pigment suitable for applications requiring regulatory compliance in food-contact plastics?
A: While not pre-approved for all food-contact regulations globally, BASF 3G-K Pigment is manufactured under strict quality control and may be evaluated for specific food-contact uses depending on regional requirements, formulation composition, and intended migration conditions. Customers are advised to conduct application-specific compliance testing.
Q5: What is the typical dosage range for BASF 3G-K Pigment in polymer coloring applications?
A: Dosage generally ranges from 0.1% to 2% by weight, depending on the desired shade intensity, polymer type, processing method, and end-use performance requirements. It is typically used at low concentrations due to its high tinctorial strength and efficient chromophore yield.
