Q1: What is the primary chemical composition of Cathay FERROTINT Black F9000?
A: Cathay FERROTINT Black F9000 is a high-performance inorganic black pigment based on a complex iron oxide–manganese oxide spinel structure, engineered for thermal stability and chemical inertness in demanding industrial applications.
Q2: Is this pigment suitable for use in high-temperature polymer processing, such as engineering thermoplastics?
A: Yes — F9000 exhibits excellent thermal stability and retains its black intensity and dispersion integrity at processing temperatures up to 300 °C, making it well-suited for polyamide, polypropylene, and other high-melt-index engineering resins.
Q3: How does F9000 compare to carbon black in terms of UV resistance and weathering performance?
A: Unlike organic blacks or standard carbon black, F9000 offers inherently superior UV stability and resistance to chalking or fading due to its fully inorganic, non-carbonaceous nature — ideal for long-term outdoor exposure in coatings and plastics.
Q4: Can F9000 be used in water-based systems such as architectural paints or aqueous inks?
A: Yes — with appropriate surface treatment and dispersion protocols, F9000 demonstrates good compatibility and colloidal stability in water-based formulations, including acrylic emulsions and latex systems.
Q5: What is the typical dosage range when incorporating F9000 into plastic masterbatches?
A: Dosage depends on the desired opacity, blackness depth, and base resin, but F9000 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — owing to its high tinting strength and efficient light absorption.
