Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YA24R?
A: Cathay CATHAYCOAT Yellow YA24R is an inorganic yellow pigment based on a modified iron oxide–zinc oxide composite system, engineered for enhanced thermal stability and chromatic consistency in high-temperature processing environments.
Q2: Is YA24R suitable for use in food-contact coatings or packaging inks?
A: YA24R is formulated for industrial and architectural coating applications. It is not certified for direct food-contact use; customers requiring compliance with food safety regulations should consult regulatory documentation and conduct application-specific migration testing under relevant jurisdictional guidelines.
Q3: How does YA24R perform under UV exposure and weathering conditions?
A: As a crystalline inorganic pigment, YA24R exhibits excellent inherent UV stability and resistance to chalking or fading, making it well-suited for exterior architectural coatings and long-term outdoor applications where color retention is critical.
Q4: Can YA24R be dispersed effectively in water-based systems?
A: Yes — YA24R is surface-treated to support stable dispersion in both water-based and solvent-based coating formulations. Optimal dispersion typically requires standard high-shear mixing or bead milling, and compatibility should be verified with specific resin/binder systems.
