Q1: What is the primary chemical composition of Cathay CATHAYCOAT Red RA14B?
A: Cathay CATHAYCOAT Red RA14B is a high-performance inorganic red pigment based on a modified iron oxide–chromium oxide composite system, engineered for enhanced thermal stability and color consistency in demanding industrial applications.
Q2: Is this pigment suitable for high-temperature coating systems such as coil coatings or powder coatings?
A: Yes — RA14B is specifically formulated to retain its chromatic integrity and dispersion stability under elevated processing temperatures, making it well-suited for coil coatings, architectural powder coatings, and other thermally cured systems.
Q3: How does RA14B compare to organic red pigments in terms of weather resistance and UV stability?
A: As an inorganic pigment, RA14B offers significantly superior resistance to UV degradation, chalking, and fading compared to most organic reds—particularly in exterior architectural and industrial maintenance coatings exposed to prolonged sunlight and moisture.
Q4: Can RA14B be used in water-based paint systems without compromising dispersion or gloss?
A: Yes — RA14B is surface-treated to ensure good wetting and stable dispersion in both water-based and solvent-based architectures, supporting consistent film formation and gloss retention across acrylic, PUD, and epoxy dispersions.
Q5: What is the typical dosage range for RA14B in industrial coating formulations?
A: Dosage depends on the required opacity, hue intensity, and base formulation, but RA14B is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — due to its high tinting strength and efficient light absorption properties.
