Q1: What is the primary chemical composition of CATHAYPURE Red R5214?
A: CATHAYPURE Red R5214 is a high-performance inorganic red pigment based on iron oxide–modified spinel-type mixed metal oxides, engineered for enhanced thermal stability and chromatic purity.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: CATHAYPURE Red R5214 is formulated for non-food-contact industrial applications. It is not certified for direct food-contact use; customers requiring food-safe pigments should consult our dedicated food-grade product portfolio and verify compliance with applicable regional regulations.
Q3: How does R5214 perform under high-temperature processing conditions?
A: This pigment exhibits excellent thermal stability, retaining color integrity during standard polymer processing—including injection molding and extrusion—up to approximately 300 °C, depending on residence time and matrix compatibility.
Q4: Can R5214 be used in water-based systems such as architectural paints or ink formulations?
A: Yes, R5214 is compatible with both solvent-based and water-based systems when properly dispersed using industry-standard surfactants or dispersing agents. Optimal performance requires formulation-specific dispersion protocols to ensure uniformity and colloidal stability.
