Q1: What is the primary application field for Graphtol Orange RL Pigment?
A: Graphtol Orange RL is specifically developed for high-performance gravure and flexographic printing inks, especially where excellent lightfastness, heat stability, and solvent resistance are required—commonly used in packaging inks for food, pharmaceutical, and premium consumer goods.
Q2: Is Graphtol Orange RL suitable for use in food-contact compliant ink systems?
A: Yes, Graphtol Orange RL is designed to support compliance with major global food-contact regulations when formulated into appropriate ink systems. Its purity profile and low extractables make it suitable for indirect food-contact applications, subject to final formulation validation and regulatory review by the ink manufacturer.
Q3: How does Graphtol Orange RL perform in aggressive solvent-based ink systems?
A: It demonstrates outstanding compatibility and dispersion stability in aromatic- and ketone-based solvent systems, maintaining color strength and rheological consistency without flocculation or viscosity drift during extended storage or high-shear processing.
Q4: What is the typical dosage range of Graphtol Orange RL in printing inks?
A: Dosage depends on formulation requirements and desired opacity or chroma, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in finished ink—due to its high tinting strength and efficient pigment utilization.
