Q1: What is the primary chemical composition of Cathay CATHAYCOAT Orange OC66?
A: Cathay CATHAYCOAT Orange OC66 is a high-performance inorganic pigment based on mixed metal oxides, engineered for thermal and chemical stability. Its exact composition is proprietary, but it contains no heavy metals such as lead, cadmium, or mercury, and complies with global regulatory expectations for restricted substances in industrial coatings.
Q2: Is OC66 suitable for high-temperature curing applications, such as coil coating or powder coating?
A: Yes — OC66 exhibits excellent thermal stability and retains its color integrity during typical industrial curing cycles up to 250 °C, making it well-suited for coil coating, powder coating, and other high-bake applications where organic pigments would degrade.
Q3: How does OC66 perform in UV-exposed outdoor applications?
A: As an inorganic oxide-based pigment, OC66 offers outstanding lightfastness and weather resistance. It demonstrates minimal fading or chalking under prolonged UV exposure, supporting long-term color retention in architectural coatings, automotive refinishing, and exterior industrial finishes.
Q4: Can OC66 be dispersed in both water-based and solvent-based systems?
A: Yes — OC66 is formulated for broad compatibility and can be effectively dispersed in aqueous, alkyd, acrylic, epoxy, and polyurethane systems using standard dispersion techniques. Optimal dispersion typically requires appropriate surfactants or dispersing aids tailored to the specific medium.
