Q1: What is the primary application area for GRAPHTOL HFG 38?
A: GRAPHTOL HFG 38 is specifically developed for high-performance gravure and flexographic printing inks used on packaging substrates, including paper, board, and certain flexible films requiring excellent gloss, transparency, and print definition.
Q2: Is GRAPHTOL HFG 38 suitable for food-contact packaging applications?
A: GRAPHTOL HFG 38 is designed to support compliance with major global food-contact regulations when formulated into inks according to good manufacturing practices. Final regulatory suitability depends on the full ink formulation, substrate, and intended use conditions — users must conduct appropriate risk assessments and obtain regulatory confirmation for their specific application.
Q3: How does GRAPHTOL HFG 38 perform in terms of dispersion stability and rheology in solvent-based ink systems?
A: The pigment exhibits excellent dispersibility in common aromatic and aliphatic solvent systems, supporting stable ink formulations with low viscosity build-up and minimal settling over time. Its optimized particle size distribution contributes to consistent jetting performance in high-speed gravure printing.
Q4: What are the recommended handling and storage conditions?
A: Store in original sealed containers in a cool, dry place away from direct sunlight and sources of heat or ignition. Avoid exposure to moisture during handling, and ensure adequate ventilation when processing the dry pigment to minimize dust generation.
