Q1: What is the primary application field for Colanyl Oxide Green G 131?
A: Colanyl Oxide Green G 131 is specifically developed for coloring solvent-based and high-solids industrial coatings, including coil coatings, can coatings, and general metal finishing systems where excellent dispersion stability and green hue consistency are required.
Q2: Is this color paste compatible with epoxy and polyester resin systems?
A: Yes, Colanyl Oxide Green G 131 demonstrates good compatibility with common thermosetting resin systems used in industrial coatings, including epoxy, polyester, and acrylic binders — though optimal performance requires preliminary compatibility testing under actual formulation conditions.
Q3: How should the paste be incorporated into a coating formulation?
A: The paste is designed for direct addition during the let-down or grinding stage. For best results, it should be added gradually under moderate shear and followed by adequate dispersion to ensure uniform distribution and avoid agglomeration.
Q4: Does Colanyl Oxide Green G 131 contain heavy metals or restricted substances?
A: This product is formulated without intentionally added lead, mercury, cadmium, or hexavalent chromium, and complies with Clariant’s internal Restricted Substances List (RSL). Final regulatory compliance depends on the full formulation and end-use application.
Q5: What is the typical dosage range for achieving standard green shades in industrial coatings?
A: Dosage is formulation-dependent, but Colanyl Oxide Green G 131 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight of the total formulation — to achieve strong green chroma with good opacity and lightfastness.
