Q1: What is the primary application field for PV Fast Orange 6RL-LHC?
A: PV Fast Orange 6RL-LHC is primarily developed for high-performance industrial coatings and plastics applications where excellent lightfastness, thermal stability, and color strength are required—especially in automotive topcoats, engineering thermoplastics, and durable outdoor finishes.
Q2: Is this pigment suitable for food-contact plastics?
A: PV Fast Orange 6RL-LHC is not certified for direct food-contact applications. It is intended for non-food-contact industrial uses; formulators requiring food-safe colorants should consult Clariant’s dedicated food-compliant pigment portfolio and verify regulatory compliance with local authorities.
Q3: How does PV Fast Orange 6RL-LHC compare to conventional orange pigments in terms of dispersion behavior?
A: This pigment exhibits good dispersibility in both polar and non-polar media due to its optimized surface treatment, enabling efficient incorporation into solvent-borne, water-borne, and polymer melt systems—typically requiring less energy input during dispersion than many legacy azo-based orange pigments.
Q4: What is the recommended dosage range in plastic masterbatches?
A: Dosage depends on formulation requirements and desired opacity or transparency, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in polyolefin or engineering plastic masterbatches.
Q5: Does this pigment contain heavy metals or halogens?
A: PV Fast Orange 6RL-LHC is a halogen-free organic pigment and contains no intentionally added heavy metals such as lead, cadmium, mercury, or hexavalent chromium, supporting compliance with major global environmental and safety initiatives including RoHS and REACH SVHC criteria.
