Q1: What is the primary application area for Hostatint Yellow E-5GD Color Paste?
A: Hostatint Yellow E-5GD is a high-performance organic pigment dispersion designed primarily for coloration of polyolefin compounds—especially injection-molded and extruded PP and HDPE parts—where excellent heat stability, lightfastness, and dispersion quality are required.
Q2: Is this color paste suitable for food-contact applications?
A: Hostatint Yellow E-5GD is formulated to meet general regulatory expectations for indirect food contact in plastics, subject to compliance with applicable regional requirements. Final approval depends on the complete formulation, processing conditions, and end-use compliance testing by the compounder or converter.
Q3: How should this paste be incorporated into polymer melts?
A: It is typically added directly to the polymer melt via gravimetric or volumetric dosing systems during compounding or masterbatch production. Good mixing efficiency and sufficient residence time ensure optimal dispersion without pigment agglomeration.
Q4: What is the typical dosage range when using this paste in polyolefins?
A: Dosage depends on the desired shade intensity and base polymer characteristics, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the final compound.
Q5: Does this product require special storage or handling precautions?
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 adequate ventilation during handling to minimize dust exposure. Refer to the Safety Data Sheet for detailed occupational hygiene guidance.
