Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YS22E?
A: YS22E is a high-performance inorganic yellow pigment based on a modified complex metal oxide system, engineered for thermal stability and chemical inertness in demanding industrial coating applications.
Q2: Is YS22E suitable for high-temperature curing processes, such as those used in coil coating or powder coating?
A: Yes — YS22E is specifically formulated to retain color integrity and dispersion stability at elevated processing temperatures, making it well-suited for both coil coating lines and thermoset powder coating systems.
Q3: How does YS22E compare to organic yellow pigments in terms of weather resistance and UV stability?
A: As an inorganic pigment, YS22E offers significantly superior resistance to UV degradation, chalking, and long-term color fade compared to conventional organic yellows — particularly in exterior architectural and industrial maintenance coatings.
Q4: Can YS22E be used in waterborne coating systems without compromising dispersion or gloss performance?
A: Yes — YS22E is surface-treated to ensure good compatibility and stable dispersion in both solvent-borne and modern waterborne acrylic and polyurethane systems, supporting consistent gloss and film uniformity.
Q5: What is the typical dosage range for optimal color strength and cost efficiency in industrial coatings?
A: Dosage depends on formulation requirements and desired opacity, but YS22E is typically used at low concentrations due to its high tinting strength — generally ranging from 0.1% to 2% by weight in finished coating systems.
