Clariant Polysynthren Yellow RL-LHC Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary application field for Polysynthren Yellow RL-LHC?

A: Polysynthren Yellow RL-LHC is a high-performance, solvent-stable organic pigment specifically developed for demanding industrial ink applications—particularly in gravure and flexographic printing inks for packaging, where excellent dispersion stability, gloss, and batch-to-batch consistency are required.

Q2: Is this pigment suitable for food-contact packaging inks?

A: Polysynthren Yellow RL-LHC is designed to meet stringent regulatory expectations for indirect food contact applications. It complies with major global frameworks for printing inks on packaging materials, subject to proper formulation, processing, and end-use conditions. Final compliance must be verified by the ink manufacturer in accordance with applicable local regulations and intended migration scenarios.

Q3: How does RL-LHC differ from standard Polysynthren Yellow RL grades?

A: The “LHC” designation indicates an optimized version with enhanced heat stability and improved resistance to solvent interaction—making it especially suitable for high-speed, high-temperature printing processes and formulations containing aggressive solvents such as ketones or esters.

Q4: What is the typical dosage range when using this pigment in solvent-based inks?

A: Dosage depends on the required color strength, transparency, and substrate, but Polysynthren Yellow RL-LHC is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in finished ink formulations—to achieve optimal performance without compromising rheology or drying behavior.

Q5: Does this pigment require special dispersion equipment or protocols?

A: For best results, high-shear dispersion using media mills or bead mills is recommended. Pre-wetting with compatible solvents and controlled temperature management during dispersion help ensure full deagglomeration and long-term colloidal stability in final ink systems.
