Q1: What is the primary chemical composition of Cathay FERROTINT Red F2100?
A: Cathay FERROTINT Red F2100 is an iron oxide-based inorganic pigment, primarily composed of hematite (α-Fe₂O₃), engineered for high chroma, thermal stability, and consistent particle morphology.
Q2: Is this pigment suitable for use in heat-sensitive polymer systems such as polyolefins or PVC?
A: Yes — F2100 exhibits excellent thermal stability and is widely used in thermoplastic and thermoset applications, including polypropylene, HDPE, and rigid PVC, without significant color shift up to typical processing temperatures.
Q3: How does F2100 compare to organic red pigments in terms of lightfastness and weather resistance?
A: As an inorganic iron oxide pigment, F2100 offers superior lightfastness, UV stability, and atmospheric resistance compared to most organic reds — making it especially suited for exterior applications and long-term color retention.
Q4: Can F2100 be dispersed in aqueous systems for architectural coatings or ink formulations?
A: Yes — F2100 is compatible with both water-based and solvent-based systems. With appropriate surfactants or dispersing agents, it achieves stable, uniform dispersion in latex paints, waterborne inks, and industrial coatings.
Q5: What is the typical dosage range when using F2100 in plastic masterbatches?
A: Dosage depends on the desired shade intensity and substrate, but F2100 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in masterbatch formulations — due to its high tinting strength and opacity.
