Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YA22B?
A: Cathay CATHAYCOAT Yellow YA22B is a high-performance inorganic yellow pigment based on modified iron oxide and/or complex metal oxide chemistry, engineered for enhanced thermal stability and lightfastness. Its exact proprietary formulation is protected, but it contains no heavy metals such as lead, cadmium, or chromium(VI).
Q2: Is YA22B suitable for high-temperature processing applications, such as engineering plastics or powder coatings?
A: Yes — YA22B is specifically developed for excellent thermal stability and maintains consistent color performance during melt processing up to approximately 280°C, making it well-suited for polyolefins, polyesters, and thermoset powder coating systems.
Q3: How does YA22B compare to organic yellow pigments in terms of weather resistance?
A: As an inorganic pigment, YA22B offers significantly superior UV resistance, chalking resistance, and long-term color retention compared to most organic yellows — especially under outdoor exposure and humid conditions — without requiring additional UV stabilizers in many standard formulations.
Q4: Can YA22B be used in water-based architectural coatings?
A: Yes — YA22B demonstrates good dispersibility and stability in both solvent-borne and water-based systems, including acrylic emulsion paints. It is compatible with common dispersants and rheology modifiers used in architectural and industrial waterborne coatings.
