Q1: What is the primary chemical composition of Cathay FERROTINT Red F2240?
A: Cathay FERROTINT Red F2240 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 thermal stability.
Q2: Is this pigment suitable for use in high-temperature polymer processing, such as polypropylene or engineering plastics?
A: Yes — F2240 exhibits excellent thermal stability and is widely used in thermoplastic applications processed at temperatures up to 300 °C, including PP, PE, and certain engineering resins, without significant color shift or decomposition.
Q3: How does F2240 compare to organic red pigments in terms of weather resistance and UV stability?
A: As an inorganic iron oxide pigment, F2240 offers inherently superior lightfastness, weather resistance, and UV stability compared to most organic reds — making it preferred for outdoor applications and long-term color retention where durability is critical.
Q4: Can F2240 be dispersed effectively in water-based systems such as architectural coatings or aqueous inks?
A: Yes — with appropriate surface treatment and standard dispersion protocols (e.g., using polyacrylate dispersants and high-shear mixing), F2240 achieves stable, uniform dispersion in water-based formulations while maintaining good tinting strength and rheological compatibility.
Q5: What is the typical dosage range when using F2240 in plastic coloration or architectural paints?
A: Dosage depends on the desired shade intensity and substrate opacity, but F2240 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in plastics and 2–8% in architectural coatings — due to its high hiding power and strong tinting strength.
