Q1: What is the primary chemical composition of Cathay FERROTINT Black F9330?
A: Cathay FERROTINT Black F9330 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 heat-sensitive polymer systems such as polyolefins or engineering thermoplastics?
A: Yes — F9330 exhibits excellent thermal stability, typically withstanding processing temperatures up to 300 °C without significant discoloration or decomposition, making it well-suited for extrusion and injection molding of polyolefins, ABS, PC, and similar resins.
Q3: How does F9330 compare to carbon black in terms of UV resistance and weathering performance?
A: Unlike organic pigments and many carbon blacks, F9330 offers inherently superior UV stability and resistance to chalking or fading due to its fully inorganic nature — it does not photodegrade and maintains consistent color integrity under prolonged outdoor exposure.
Q4: Can F9330 be used in water-based coatings and inks?
A: Yes — with appropriate surface treatment and dispersion protocols, F9330 demonstrates good compatibility and stability in aqueous systems, including architectural paints, industrial coatings, and water-based flexographic or gravure inks.
Q5: What is the typical dosage range for achieving full opacity and jet-black tone in plastic applications?
A: Dosage depends on formulation requirements and desired opacity, but F9330 is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight in most thermoplastic and thermoset matrices.
