Q1: What is the primary application area for GRAPHTOL LC 53 1?
A: GRAPHTOL LC 53 1 is specifically developed for high-performance gravure and flexographic inks used in packaging applications, particularly where excellent gloss, transparency, and ink film integrity are required on flexible substrates such as films and foils.
Q2: Is GRAPHTOL LC 53 1 suitable for food-contact compliant inks?
A: Yes — GRAPHTOL LC 53 1 is manufactured under Clariant’s stringent quality control systems and is designed to support compliance with major global food-contact regulations when formulated into inks by qualified ink manufacturers. Final regulatory compliance depends on the full ink formulation and intended application conditions.
Q3: How does GRAPHTOL LC 53 1 compare to other pigments in terms of dispersion stability in solvent-based systems?
A: GRAPHTOL LC 53 1 exhibits excellent dispersibility and long-term stability in common solvent-based ink vehicles, including ester-, ketone-, and aromatic hydrocarbon-based systems. Its optimized surface treatment helps minimize flocculation and maintains consistent color strength and rheology during storage and printing.
Q4: What is the typical dosage range for GRAPHTOL LC 53 1 in ink formulations?
A: Dosage depends on the desired color strength, substrate, and print process, but GRAPHTOL LC 53 1 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in finished ink — due to its high tinctorial strength and efficient light absorption.
