Q1: What is the primary chemical composition of Cathay FERROTINT Red F4400?
A: Cathay FERROTINT Red F4400 is an inorganic iron oxide-based red pigment, primarily composed of hematite (α-Fe₂O₃), engineered for high thermal stability and consistent chromatic performance in demanding industrial applications.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Cathay FERROTINT Red F4400 is not certified for direct food-contact applications. It is intended for general industrial uses such as construction materials, architectural coatings, and non-regulated plastic masterbatches where regulatory compliance with food-contact standards is not required.
Q3: How does F4400 perform under high-temperature processing conditions?
A: As a thermally stable inorganic oxide pigment, F4400 retains its color integrity and structural integrity during high-temperature processing—such as extrusion, calendering, or ceramic firing—without significant fading, blooming, or decomposition.
Q4: Can F4400 be dispersed in water-based systems?
A: Yes, F4400 can be effectively dispersed in water-based systems with appropriate surfactants and dispersion aids. Its surface treatment supports good wetting and stabilization in aqueous media used for architectural paints, cementitious products, and latex formulations.
Q5: What is the typical dosage range when using F4400 in polymer compounds?
A: Dosage depends on the desired opacity, color strength, and base polymer matrix, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—to achieve optimal color development without compromising mechanical properties.
