Q1: What is the primary chemical class and hue characteristic of Hansa 10G?
A: Hansa 10G is an organic monoazo pigment belonging to the yellow shade family, offering a clean, greenish-yellow tone with good brightness and moderate transparency in many application media.
Q2: Is Hansa 10G suitable for use in food-contact plastics or inks?
A: Hansa 10G is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for general-purpose industrial uses such as non-food packaging inks, coatings, and engineering plastics where regulatory compliance for food contact is not required.
Q3: How does Hansa 10G perform in terms of heat stability and lightfastness?
A: Hansa 10G exhibits moderate heat stability, typically suitable for processing temperatures up to approximately 160–180 °C depending on residence time and matrix. Its lightfastness is moderate—generally rated between 4–5 on the ISO 105-B02 scale in standard acrylic binders—but may vary significantly with dispersion quality, film thickness, and surrounding formulation components.
Q4: What are typical dosage ranges and dispersion recommendations?
A: Hansa 10G is typically used at low concentrations, generally ranging from 0.1% to 2% by weight depending on the desired shade strength and application medium. Optimal performance requires thorough dispersion using high-shear mixing or bead milling—especially in demanding systems like solvent-based inks or PVC pastes—to achieve full color development and avoid flocculation.
