Q1: What is the primary chemical class and typical application field for Hansa Yellow 10G?
A: Hansa Yellow 10G is an organic monoazo pigment, widely used in industrial coatings, printing inks, and plastics where bright, clean yellow shades with good lightfastness and heat stability are required.
Q2: Is Hansa Yellow 10G suitable for food-contact applications?
A: Hansa Yellow 10G is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial uses; customers requiring food-safe colorants should consult Clariant’s certified food-grade pigment portfolio.
Q3: How does Hansa Yellow 10G perform in thermoplastic processing?
A: This pigment demonstrates good thermal stability up to typical processing temperatures for polyolefins and PVC, with minimal shade shift or degradation when properly dispersed. Performance may vary depending on residence time, shear conditions, and polymer matrix.
Q4: What dispersion methods are recommended for optimal color development?
A: High-shear dispersion using appropriate equipment—such as three-roll mills, bead mills, or high-speed dispersers—is recommended. Pre-wetting with compatible solvents or resins enhances deagglomeration and ensures uniform distribution in the final medium.
