Q1: What is the primary chemical composition of Cathay CATHAYCOAT Red RC16?
A: Cathay CATHAYCOAT Red RC16 is an iron oxide-based inorganic pigment, formulated to deliver stable, heat-resistant red coloration with low reactivity in demanding industrial coating systems.
Q2: Is RC16 suitable for high-temperature curing applications, such as powder coatings or coil coatings?
A: Yes — RC16 exhibits excellent thermal stability and retains its color integrity during typical industrial curing cycles up to 200 °C, making it well-suited for powder coatings, coil coatings, and other thermoset systems requiring robust pigment performance.
Q3: How does RC16 perform in terms of UV resistance and weathering stability?
A: As a crystalline iron oxide pigment, RC16 offers inherently strong UV resistance and long-term outdoor durability, with minimal fading or chalking observed in properly formulated exterior architectural and industrial maintenance coatings.
Q4: Can RC16 be used in waterborne coating systems without compromising dispersion stability or tinting strength?
A: Yes — RC16 is surface-treated to support effective wetting and stabilization in both solvent-borne and waterborne systems. Optimal dispersion typically requires standard high-shear mixing, and performance is maintained across pH ranges common in acrylic and PUD-based formulations.
Q5: What safety and regulatory considerations apply to handling and use of RC16?
A: RC16 is classified as a non-hazardous inorganic pigment under standard transport and handling guidelines. It contains no heavy metals of concern (e.g., lead, cadmium, mercury) and complies with major global restrictions on restricted substances for general industrial coating applications.
