Q1: What is the primary chemical composition of Cathay CATHAYCOAT Red RA14?
A: Cathay CATHAYCOAT Red RA14 is an inorganic iron-based pigment, formulated as a modified iron oxide complex with enhanced thermal and chemical stability. It does not contain heavy metals such as lead, cadmium, or chromium(VI), aligning with modern environmental and regulatory expectations for industrial pigments.
Q2: Is this pigment suitable for high-temperature coating applications?
A: Yes — RA14 exhibits excellent thermal stability and retains its color integrity under prolonged exposure to temperatures up to 600°C, making it well-suited for ceramic glazes, heat-resistant industrial coatings, and exhaust system finishes where organic pigments would degrade.
Q3: How does RA14 perform in acidic or alkaline environments?
A: RA14 demonstrates good resistance to both mild acidic and alkaline conditions typical of architectural and protective coating systems. However, extended exposure to strong mineral acids or highly caustic media may affect dispersion stability and should be evaluated in context-specific formulation trials.
Q4: Can RA14 be used in water-based coating systems?
A: Yes — RA14 is compatible with aqueous dispersions and can be effectively incorporated into water-based acrylic, epoxy, and polyurethane systems using appropriate surfactants and dispersing agents. Pre-wetting and controlled shear mixing are recommended to ensure optimal deagglomeration and long-term colloidal stability.
