Q1: What is the primary chemical composition of Cathay FLOWTINT Brown FF8860?
A: Cathay FLOWTINT Brown FF8860 is an iron oxide-based inorganic pigment, formulated with stabilized α-Fe₂O₃ as the principal colorant, combined with controlled surface treatments to enhance dispersion and compatibility in polymer and coating systems.
Q2: Is this pigment suitable for use in food-contact plastics or packaging applications?
A: Cathay FLOWTINT Brown FF8860 is designed for general industrial applications including architectural coatings, construction materials, and non-food-contact plastics. It is not pre-qualified for direct food-contact use; regulatory compliance must be verified case-by-case with end-product testing and relevant local authority requirements.
Q3: How does FF8860 perform under high-temperature processing conditions, such as injection molding or extrusion?
A: As a thermally stable inorganic oxide pigment, FF8860 exhibits excellent resistance to thermal degradation up to typical polymer processing temperatures (e.g., ≤280°C), maintaining consistent color and minimal gas evolution—making it well-suited for polyolefins, PVC, and engineering thermoplastics.
Q4: What are the recommended dispersion methods for optimal color development in liquid systems?
A: For liquid coatings and inks, high-shear mixing or bead milling is recommended to achieve full deagglomeration. Pre-wetting with compatible solvents or resins prior to incorporation helps improve wetting efficiency and reduces viscosity spikes during dispersion.
