Q1: What is the primary chemical composition of Cathay CATHAYPURE Red R2130?
A: Cathay CATHAYPURE Red R2130 is an iron oxide-based inorganic pigment, primarily composed of hematite (α-Fe₂O₃), engineered for high chroma, thermal stability, and consistent particle morphology.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Yes — Cathay CATHAYPURE Red R2130 is manufactured under strict quality control to meet general requirements for pigments used in food-contact applications. Final regulatory compliance depends on the complete formulation, processing conditions, and applicable regional regulations.
Q3: How does R2130 perform under high-temperature processing conditions?
A: This pigment exhibits excellent thermal stability and retains its color integrity during standard polymer processing, including extrusion and injection molding at temperatures up to approximately 300 °C, depending on residence time and atmosphere.
Q4: Can R2130 be dispersed effectively in both polar and non-polar systems?
A: Yes — with appropriate surface treatment and dispersion protocols, R2130 achieves stable dispersion in a wide range of media, including PVC, polyolefins, engineering thermoplastics, and water-based coatings. Optimal dispersion typically requires mechanical energy input and compatible dispersants.
Q5: What are the recommended storage conditions to maintain pigment performance?
A: Store in a cool, dry, well-ventilated area away from direct sunlight and sources of moisture or contamination. Keep containers tightly sealed to prevent agglomeration or dust exposure. No special climate-controlled conditions are required under normal ambient storage.
