Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YA22E?
A: Cathay CATHAYCOAT Yellow YA22E is a high-performance inorganic yellow pigment based on a stabilized complex of iron oxide and hydrated silica, engineered for thermal and chemical stability in demanding industrial applications.
Q2: Is YA22E suitable for use in high-temperature coating systems, such as coil coatings or powder coatings?
A: Yes — YA22E exhibits excellent thermal stability and retains its color integrity at temperatures exceeding 200 °C, making it well-suited for baked enamel, coil coating, and thermoset powder coating formulations.
Q3: How does YA22E compare to organic yellow pigments in terms of lightfastness and weather resistance?
A: As an inorganic pigment, YA22E delivers significantly superior lightfastness, UV resistance, and long-term outdoor durability compared to most organic yellows — with minimal fading or chalking under prolonged exposure to sunlight and moisture.
Q4: Can YA22E be used in water-based industrial paint systems without compromising dispersion stability?
A: Yes — YA22E is surface-treated for compatibility with both water-based and solvent-based systems. When properly dispersed using standard high-shear mixing or grinding techniques, it achieves stable, uniform dispersions with low viscosity impact and minimal settling.
Q5: What is the typical dosage range for YA22E in architectural and industrial coatings?
A: Dosage depends on the required opacity, hue strength, and application method, but YA22E is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in finished coating formulations.
