Q1: What is the primary chemical composition of Cathay FERROTINT Red F4800?
A: Cathay FERROTINT Red F4800 is an iron oxide-based inorganic pigment, primarily composed of hematite (α-Fe₂O₃), engineered for high color strength, thermal stability, and chemical inertness in demanding industrial applications.
Q2: Is this pigment suitable for use in heat-sensitive polymer systems such as polyolefins or PVC?
A: Yes — F4800 exhibits excellent thermal stability and is routinely processed in extrusion and injection molding operations up to 250 °C. Its inorganic nature ensures minimal degradation and color shift during high-shear, high-temperature compounding.
Q3: How does F4800 compare to organic red pigments in terms of weather resistance and UV stability?
A: As an inorganic iron oxide pigment, F4800 offers inherently superior lightfastness, UV resistance, and atmospheric stability compared to most organic reds — making it preferred for exterior applications, architectural coatings, and long-life plastic products exposed to sunlight and moisture.
Q4: Can F4800 be used in water-based coating systems without dispersion additives?
A: While F4800 is compatible with aqueous systems, optimal performance requires appropriate wetting and dispersing agents to ensure stable suspension, uniform color development, and long-term rheological control. Pre-dispersed versions or in-house dispersion protocols are recommended for consistent results.
Q5: What is the typical dosage range when using F4800 in plastic masterbatches?
A: Dosage depends on the desired shade intensity and base polymer, but F4800 is generally used at low concentrations — typically ranging from 0.1% to 2% by weight — due to its high tinting strength and efficient opacity development.
