Q1: What are the primary application areas for Hansa Brilliant Yellow 2GX 72-S?
A: This pigment is widely used in solvent-based and water-based industrial coatings, including automotive refinishes, general industrial paints, and coil coatings. It is also suitable for selected plastic applications where good lightfastness and heat stability up to moderate processing temperatures are required.
Q2: How does this pigment perform in terms of lightfastness and weather resistance?
A: Hansa Brilliant Yellow 2GX 72-S offers good to very good lightfastness in most binder systems, particularly in acrylic and alkyd media. Its weather resistance is moderate and benefits from UV stabilizers in demanding outdoor applications.
Q3: Is this pigment suitable for food-contact plastics or inks?
A: No — Hansa Brilliant Yellow 2GX 72-S is not approved for direct food-contact applications. It is intended for non-food-related industrial uses only. For food-contact compliance, consult Clariant’s portfolio of certified pigments and request appropriate regulatory documentation.
Q4: What is the typical dosage range when using this pigment in coatings?
A: Dosage depends on formulation requirements and desired shade strength, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to the total formulation — with optimal dispersion being critical for consistent color development and performance.
