Q1: What is the primary chemical composition of Cathay FERROTINT Red F2320?
A: Cathay FERROTINT Red F2320 is an iron oxide-based inorganic pigment, primarily composed of hematite (α-Fe₂O₃), engineered for high chroma, thermal stability, and consistent red hue in demanding industrial applications.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Cathay FERROTINT Red F2320 is designed for general industrial applications including construction materials, architectural coatings, and non-food-contact plastics. It is not certified for direct food-contact use; customers requiring food-safe pigments should consult regulatory-compliant alternatives and conduct appropriate migration testing per applicable jurisdiction.
Q3: How does F2320 perform under elevated temperature conditions?
A: As a thermally stable inorganic oxide pigment, F2320 maintains its color integrity and structural stability during standard polymer processing (e.g., extrusion, injection molding) and baking cycles in coatings—typically up to 300 °C without significant hue shift or decomposition.
Q4: Can F2320 be dispersed in water-based systems?
A: Yes—F2320 is compatible with both aqueous and solvent-based formulations. For optimal dispersion in water-based systems, proper wetting agents and dispersants are recommended, along with mechanical stabilization (e.g., bead milling or high-shear mixing) to achieve uniform color development and long-term suspension stability.
Q5: What is the typical dosage range when using F2320 in architectural coatings?
A: Dosage depends on desired opacity, shade depth, and binder system, but F2320 is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to total formulation—to achieve strong red tones while maintaining cost efficiency and rheological balance.
