Q1: What is the primary chemical class of Solvaperm Red 2G-LHC?
A: Solvaperm Red 2G-LHC is a high-performance, solvent-stable azo pigment designed for demanding non-aqueous applications. It is not a dye or a metal complex pigment, but rather a chemically stabilized organic pigment with enhanced thermal and light stability.
Q2: Is this pigment suitable for food-contact inks or coatings?
A: Solvaperm Red 2G-LHC is not specifically developed or certified for direct food-contact applications. Its use in food packaging inks or coatings must be evaluated case-by-case based on full formulation compliance, regulatory jurisdiction, and migration testing — Clariant does not provide food-contact clearance documentation for this grade.
Q3: How does Solvaperm Red 2G-LHC compare to standard azo red pigments in terms of heat stability?
A: This pigment exhibits significantly improved thermal stability compared to conventional monoazo reds, enabling safe processing in high-temperature extrusion and calendering operations typical for plastic coloration — particularly in polyolefins and PVC compounds.
Q4: What types of solvents or resin systems is Solvaperm Red 2G-LHC typically compatible with?
A: It demonstrates excellent compatibility with common aromatic and aliphatic hydrocarbon solvents, nitrocellulose-based lacquers, acrylic resins, and chlorinated rubber systems — making it well-suited for gravure and flexographic inks, as well as industrial coatings.
Q5: What is the typical dosage range when using this pigment in solvent-based inks?
A: Dosage depends on formulation requirements and desired shade strength, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to total ink solids — due to its high tinting strength and efficient dispersion characteristics.
