Q1: What is the primary chemical composition of Cathay FERROTINT Red F2120?
A: Cathay FERROTINT Red F2120 is a high-performance inorganic iron oxide-based red pigment, primarily composed of α-Fe₂O₃ (hematite) with controlled crystallinity and particle morphology to ensure consistent color strength and dispersion stability.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Cathay FERROTINT Red F2120 is formulated for industrial and general-purpose applications. While it meets common purity and heavy metal limits for non-food-grade pigments, it is not pre-certified for direct food contact. Customers requiring food-contact compliance must conduct full regulatory validation per their target market and application.
Q3: How does F2120 compare to organic red pigments in terms of heat stability?
A: As an inorganic iron oxide pigment, F2120 offers superior thermal stability compared to most organic reds—retaining color integrity at processing temperatures commonly encountered in polyolefin extrusion, powder coating curing, and ceramic firing, without significant charring or hue shift.
Q4: What dispersion methods are recommended for optimal performance in solvent-based systems?
A: For solvent-based coatings and inks, F2120 responds well to high-shear dispersion using suitable wetting agents and dispersants. Pre-wetting with polar solvents followed by bead milling or high-speed stirrer dispersion typically achieves optimal deagglomeration and color development.
