Q1: What is the primary chemical composition of Cathay FERROTINT Red F2325?
A: Cathay FERROTINT Red F2325 is a high-performance inorganic iron oxide-based red pigment, primarily composed of α-Fe₂O₃ with controlled crystallinity and particle morphology to ensure optimal color strength, thermal stability, and UV resistance.
Q2: Is this pigment suitable for use in high-temperature polymer processing applications?
A: Yes — F2325 exhibits excellent thermal stability and is routinely used in engineering thermoplastics such as polyamide, polypropylene, and polyester processed at temperatures up to 280 °C without significant color shift or decomposition.
Q3: How does F2325 compare to organic red pigments in terms of weathering performance?
A: As an inorganic iron oxide pigment, F2325 offers significantly superior lightfastness, chalk resistance, and long-term outdoor durability compared to most organic reds — making it preferred for exterior coatings, architectural concrete, and agricultural films.
Q4: Can F2325 be dispersed effectively in water-based systems?
A: Yes — with appropriate surfactant selection and dispersion protocols, F2325 achieves stable, low-viscosity dispersions in aqueous media, including architectural paints, cementitious slurries, and waterborne industrial coatings.
