Q1: What is the primary application area for GRAPHTOL H2R 139?
A: GRAPHTOL H2R 139 is specifically developed for high-performance gravure and flexographic inks used in packaging applications, particularly where excellent rub resistance, gloss retention, and pigment dispersion stability are required.
Q2: Is GRAPHTOL H2R 139 suitable for food-contact packaging inks?
A: Yes — GRAPHTOL H2R 139 is designed to meet stringent regulatory expectations for indirect food contact applications. It complies with relevant global guidelines for pigments in packaging inks, including those referenced in FDA 21 CFR and EU Framework Regulation (EC) No 1935/2004, subject to final formulation compliance and migration testing.
Q3: How does GRAPHTOL H2R 139 perform in solvent-based versus water-based ink systems?
A: GRAPHTOL H2R 139 demonstrates robust compatibility and dispersion stability in conventional solvent-based gravure inks. While it can be adapted for water-based systems with appropriate dispersants and processing, optimal performance—especially in terms of gloss and film integrity—is typically achieved in solvent-borne formulations.
Q4: What is the recommended dosage range for GRAPHTOL H2R 139 in ink formulations?
A: Dosage depends on the desired color strength, substrate, and print process, but GRAPHTOL H2R 139 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in the finished ink—to achieve strong chroma and consistent print quality without compromising rheology or drying behavior.
