Q1: What is the primary chemical composition of Cathay FERROTINT Red F2150?
A: Cathay FERROTINT Red F2150 is an iron oxide-based inorganic pigment, primarily composed of hematite (α-Fe₂O₃), engineered for high color strength, thermal stability, and chemical inertness in demanding industrial applications.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Cathay FERROTINT Red F2150 is designed for general industrial applications including construction materials, architectural coatings, and polymer masterbatches. It is not pre-qualified for direct food-contact use; customers must conduct full regulatory assessment and migration testing aligned with their target market requirements before such application.
Q3: How does F2150 perform under high-temperature processing conditions?
A: As a thermally stable inorganic oxide pigment, F2150 maintains its color integrity and structural stability during standard polymer processing—including extrusion and injection molding—without significant degradation or gas evolution up to approximately 350°C, depending on residence time and atmosphere.
Q4: Can F2150 be dispersed effectively in water-based systems?
A: Yes—F2150 can be successfully incorporated into aqueous systems such as architectural paints and cementitious slurries, typically requiring appropriate dispersants and mechanical stabilization. Its surface chemistry supports good wetting and dispersion when formulated with conventional anionic or nonionic surfactants.
