Q1: What are the primary application areas for Hansa Brilliant Yellow 2GX70 74?
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 shade are required. It is not recommended for outdoor architectural coatings or applications demanding exceptional weather resistance.
Q2: How does Hansa Brilliant Yellow 2GX70 74 compare to other monoazo yellow pigments in terms of heat stability?
A: It offers moderate thermal stability suitable for standard extrusion processes in polyolefins and PVC, but may undergo slight shade shift above 180 °C. For high-temperature engineering polymers like polyesters or polycarbonates, alternative high-stability pigments are generally preferred.
Q3: Is this pigment suitable for food-contact plastic applications?
A: Hansa Brilliant Yellow 2GX70 74 is not approved for direct food-contact applications under major global regulatory frameworks. Customers requiring food-safe colorants should consult Clariant’s portfolio of certified food-contact pigments and verify compliance with applicable regional requirements.
Q4: What dispersion characteristics can be expected in solvent-based ink systems?
A: The pigment exhibits good wetting and dispersibility in common aromatic and aliphatic hydrocarbon solvents, as well as ester- and ketone-based systems. Optimal performance typically requires standard high-speed dispersing or bead-milling; stabilization with appropriate resin vehicles is recommended to maintain gloss and rheological stability.
