Q1: What is the primary chemical composition of Cathay FERROTINT Red F2140?
A: Cathay FERROTINT Red F2140 is an iron oxide-based inorganic pigment, primarily composed of hematite (α-Fe₂O₃), engineered for high chroma, thermal stability, and UV resistance in demanding industrial applications.
Q2: Is this pigment suitable for use in plastics processing, such as injection molding or extrusion?
A: Yes — F2140 is specifically formulated for high-temperature polymer processing. It demonstrates excellent dispersion stability and retains color integrity under typical melt processing conditions for polyolefins, engineering thermoplastics, and PVC.
Q3: How does F2140 compare to organic red pigments in terms of weathering performance?
A: As an inorganic iron oxide, F2140 offers significantly superior lightfastness, UV stability, and resistance to atmospheric degradation compared to most organic reds — making it preferred for long-term outdoor applications such as architectural coatings and exterior plastic components.
Q4: Can F2140 be used in water-based systems like architectural paints or latex dispersions?
A: Yes — with appropriate surface treatment and dispersion protocols, F2140 achieves stable suspension and consistent tinting strength in aqueous systems, including acrylic emulsions and mineral-based plasters.
