Q1: What is the primary chemical composition of Cathay CATHAYCOAT Red RC11?
A: Cathay CATHAYCOAT Red RC11 is a high-performance inorganic red pigment based on a stabilized iron oxide–chromium oxide solid solution system, engineered for thermal and chemical robustness in demanding coating applications.
Q2: Is RC11 suitable for use in high-temperature curing systems, such as powder coatings or coil coatings?
A: Yes — RC11 exhibits excellent thermal stability and retains its color integrity during typical industrial curing cycles up to 250 °C, making it well-suited for powder coatings, coil coatings, and other thermally processed systems.
Q3: How does RC11 perform in terms of weather resistance and UV stability?
A: As an inorganic pigment with a dense crystalline structure, RC11 delivers outstanding resistance to UV radiation, moisture, and atmospheric pollutants, ensuring long-term color retention in exterior architectural and industrial coatings.
Q4: Can RC11 be used in water-based coating systems without compromising dispersion stability or tinting strength?
A: Yes — RC11 is surface-treated to enhance compatibility and dispersibility in both water-based and solvent-based systems. Optimal performance requires proper wetting and stabilization during dispersion, typically achieved using conventional polymeric or ionic dispersants.
Q5: What is the recommended dosage range for achieving full opacity and consistent color development?
A: Dosage depends on the specific formulation and desired opacity, but RC11 is typically used at low concentrations due to its high hiding power — generally ranging from 0.1% to 2% by weight in finished coating systems.
