Q1: What is the primary application field for Graphtol Yellow H2R?
A: Graphtol Yellow H2R is specifically developed for high-performance gravure and flexographic inks used in packaging applications, particularly where excellent lightfastness, heat stability, and solvent resistance are required.
Q2: Is Graphtol Yellow H2R suitable for food-contact packaging inks?
A: Yes — Graphtol Yellow H2R is designed to meet stringent regulatory expectations for non-migrating pigments in food packaging inks. It complies with major global frameworks for printing ink pigments, including FDA 21 CFR and EU guidelines for indirect food contact, subject to final formulation validation.
Q3: How does Graphtol Yellow H2R perform in aggressive solvent systems?
A: This pigment demonstrates robust resistance to common gravure solvents such as toluene, ethyl acetate, and alcohol-based blends, maintaining color strength and dispersion stability without significant flocculation or hue shift under typical processing conditions.
Q4: What is the recommended dosage range in ink formulations?
A: Dosage depends on the desired opacity, substrate, and print process, but Graphtol Yellow H2R is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in finished ink systems — due to its high tinting strength and efficient dispersion characteristics.
