Q1: What are the primary application areas for Hansa Brilliant Yellow 5GX 03?
A: This pigment is widely used in industrial coatings, printing inks (especially offset and gravure), and plastics applications where high brightness, good lightfastness, and clean yellow hue are required. It is not recommended for applications requiring food-contact compliance or outdoor weathering resistance without additional stabilization.
Q2: How does Hansa Brilliant Yellow 5GX 03 compare to other Hansa yellows in terms of heat stability?
A: It offers moderate thermal stability suitable for standard extrusion and injection molding processes in polyolefins and PVC, but performance diminishes above 180–200 °C depending on residence time and matrix. For high-heat polymers like engineering resins, alternative pigment classes are generally preferred.
Q3: Is this pigment suitable for water-based systems?
A: Yes — Hansa Brilliant Yellow 5GX 03 is commonly formulated into aqueous dispersions for use in water-based inks and architectural coatings. Optimal dispersion requires appropriate surfactants and milling conditions to ensure colloidal stability and consistent color development.
Q4: What is the typical dosage range when using this pigment in plastic masterbatches?
A: Dosage depends on formulation requirements and desired opacity or transparency, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in final plastic articles. Higher loadings may be needed for opaque applications, while transparent tints often require precise sub-0.5% dosing.
