Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YA23E?
A: Cathay CATHAYCOAT Yellow YA23E is a high-performance inorganic yellow pigment based on a modified iron oxide–zinc oxide composite system, engineered for enhanced thermal stability and lightfastness in demanding industrial coatings.
Q2: Is YA23E suitable for high-temperature curing applications, such as powder coatings or coil coatings?
A: Yes — YA23E is specifically formulated to retain color integrity and dispersion stability under prolonged exposure to temperatures up to 250 °C, making it well-suited for thermoset powder coatings, coil coating lines, and other high-bake industrial finishing processes.
Q3: How does YA23E compare to organic yellow pigments in terms of weather resistance?
A: As an inorganic pigment, YA23E offers significantly superior UV resistance, chalking resistance, and long-term color retention compared to most organic yellows — particularly in exterior architectural and automotive OEM applications where extended durability is critical.
Q4: What are the recommended dispersion methods for optimal performance in liquid coatings?
A: For best results, disperse YA23E using high-shear mixing or bead milling with standard coating-grade dispersants. Pre-wetting with polar solvents or resin solutions prior to grinding helps achieve uniform particle distribution and maximizes tinting strength and gloss consistency.
Q5: Can YA23E be used in waterborne systems without compromising stability or color development?
A: Yes — YA23E is compatible with both solvent-borne and waterborne industrial coating systems, including acrylic, polyurethane, and epoxy dispersions. Its surface treatment ensures good wetting and colloidal stability in aqueous media when formulated with appropriate surfactants and pH control.
