Q1: What is the primary chemical composition of CATHAYRED RA14YD?
A: CATHAYRED RA14YD is a high-performance inorganic red pigment based on a modified iron oxide–chromium oxide solid solution system, engineered for enhanced thermal stability and color consistency in demanding processing environments.
Q2: Is CATHAYRED RA14YD suitable for use in food-contact plastics?
A: Yes — it is formulated to meet general requirements for pigments in food-contact applications, including compliance with major global regulatory frameworks for heavy metals and extractables. Final suitability must be confirmed through end-product testing per applicable regional regulations.
Q3: How does CATHAYRED RA14YD perform under high-temperature processing conditions?
A: It exhibits excellent thermal stability, retaining color integrity and minimal degradation up to 1000°C in air, making it well-suited for high-heat polymer processing (e.g., engineering thermoplastics), ceramic glazes, and refractory coatings.
Q4: What dispersion methods are recommended for optimal performance in polymer systems?
A: For best results, pre-dispersion using high-shear mixing or twin-screw compounding is recommended. Surface treatment compatibility allows effective incorporation into both polar and non-polar resins without requiring additional dispersants in most standard formulations.
