Q1: What is the primary application field for Graphtol H2R?
A: Graphtol H2R is specifically developed for high-performance industrial coatings and inks where excellent heat stability, lightfastness, and dispersibility are required—particularly in automotive refinish, coil coating, and premium packaging inks.
Q2: Is Graphtol H2R suitable for food-contact applications?
A: Graphtol H2R is not intended or certified for direct food-contact applications. It is designed for non-food-related industrial uses; customers requiring food-safe pigments should consult Clariant’s dedicated food-contact compliant product portfolio.
Q3: How does Graphtol H2R perform under elevated temperature conditions?
A: Graphtol H2R exhibits good thermal stability, enabling reliable performance during high-temperature curing processes typical of industrial baking enamels and powder coatings—without significant hue shift or decomposition.
Q4: What types of resin systems is Graphtol H2R compatible with?
A: Graphtol H2R demonstrates broad compatibility with common industrial binder systems including acrylics, polyesters, alkyds, epoxy esters, and urethane-modified resins—though optimal dispersion and stability require formulation-specific optimization.
Q5: What is the typical dosage range for Graphtol H2R in coatings formulations?
A: Dosage depends on the desired shade intensity and application requirements, but Graphtol H2R is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to total formulation solids.
