Q1: What is the primary application area for GRAPHTOL GG?
A: GRAPHTOL GG is specifically engineered for high-performance gravure and flexographic inks used in packaging applications, particularly where excellent dispersion stability, gloss, and print definition are required.
Q2: Is GRAPHTOL GG suitable for food-contact packaging inks?
A: Yes — GRAPHTOL GG is designed to meet stringent regulatory expectations for indirect food contact applications when formulated into compliant ink systems and processed under appropriate Good Manufacturing Practices (GMP).
Q3: How does GRAPHTOL GG perform in terms of heat stability during ink drying or lamination?
A: GRAPHTOL GG exhibits robust thermal stability under typical industrial drying conditions (e.g., hot-air or IR drying), maintaining color integrity and minimizing degradation risk in high-speed printing and post-printing processes such as lamination.
Q4: What solvent systems is GRAPHTOL GG typically compatible with?
A: GRAPHTOL GG demonstrates good compatibility with common low- to medium-polarity solvent blends used in gravure and flexo inks, including ester-, ketone-, and aromatic-based systems; optimal dispersion is achieved using standard pigment dispersants and milling protocols.
Q5: What is the recommended dosage range for GRAPHTOL GG in ink formulations?
A: Dosage depends on formulation requirements and desired color strength, but GRAPHTOL GG is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in the finished ink — due to its high tinctorial strength and efficient dispersion characteristics.
