Q1: What is the primary chemical composition of Cathay CATHAYCOAT Red RS16?
A: Cathay CATHAYCOAT Red RS16 is a high-performance inorganic red pigment based on modified iron oxide and mixed metal oxides, engineered for enhanced thermal stability and color consistency in demanding industrial applications.
Q2: Is this pigment suitable for use in high-temperature coating systems?
A: Yes — RS16 is specifically formulated for excellent thermal stability and retains its color integrity in organic and inorganic coating systems processed up to approximately 800 °C, making it well-suited for ceramic glazes, heat-resistant paints, and industrial enamels.
Q3: How does RS16 compare to conventional iron oxide red pigments in terms of dispersion and tinting strength?
A: RS16 offers superior dispersion characteristics in both aqueous and solvent-based media due to controlled particle size distribution and surface treatment. Its optimized crystallinity and morphology deliver higher tinting strength and improved opacity compared to standard hematite-based reds.
Q4: Can RS16 be used in food-contact or pharmaceutical packaging coatings?
A: While RS16 complies with general industrial safety and handling guidelines, it is not pre-qualified for direct food-contact or pharmaceutical applications unless specifically validated by the end-user’s regulatory team and aligned with applicable regional requirements for pigments in such uses.
Q5: What is the recommended dosage range for optimal performance in architectural and industrial coatings?
A: Dosage depends on formulation requirements and desired chroma, but RS16 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — to achieve strong, uniform red tones without compromising film integrity or weather resistance.
