Q1: What is the primary chemical composition of Cathay FERROTINT Red F4600?
A: Cathay FERROTINT Red F4600 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 — F4600 exhibits excellent thermal stability and is routinely processed in extrusion and injection molding applications up to 250°C without significant hue shift or decomposition, making it well-suited for polyolefins, PVC, and engineering thermoplastics.
Q3: How does F4600 compare to organic red pigments in terms of weathering and UV resistance?
A: As an inorganic iron oxide pigment, F4600 offers inherently superior lightfastness, UV stability, and atmospheric resistance compared to most organic reds — it shows negligible fading under prolonged outdoor exposure and maintains performance in demanding exterior applications.
Q4: Can F4600 be used in solvent-based coatings and waterborne systems?
A: Yes — F4600 is compatible with both solvent-based and waterborne formulations, including acrylic, alkyd, epoxy, and polyurethane systems. Its surface treatment ensures good dispersibility and minimal impact on rheology or gloss retention.
Q5: What is the typical dosage range when using F4600 in plastic coloration?
A: Dosage depends on the required opacity, shade intensity, and base resin, but F4600 is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight in most thermoplastic and thermoset applications.
