Q1: What is the primary chemical composition of Cathay CATHAYCOAT Red RC14B?
A: Cathay CATHAYCOAT Red RC14B is a high-performance inorganic red pigment based on a stabilized iron oxide–chromium oxide composite system, engineered for thermal and chemical robustness in demanding coating applications.
Q2: Is RC14B suitable for use in high-temperature curing coatings?
A: Yes — RC14B exhibits excellent thermal stability and retains its color integrity during standard industrial baking processes, including coil coating and powder coating cure cycles up to 250 °C.
Q3: How does RC14B perform in UV-exposed exterior coatings?
A: RC14B offers superior lightfastness and weather resistance due to its inorganic crystalline structure, making it well-suited for long-term outdoor applications such as architectural metal cladding and automotive refinish primers.
Q4: Can RC14B be dispersed in both water-based and solvent-based systems?
A: Yes — RC14B is formulated for broad compatibility and can be effectively dispersed in aqueous dispersions, acrylic emulsions, alkyds, polyurethanes, and epoxy resin systems using conventional milling and stabilization techniques.
Q5: What is the typical dosage range for optimal color development and opacity?
A: Dosage depends on formulation requirements and desired chroma, but RC14B is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — to achieve strong tinting strength and hiding power without compromising film integrity.
