Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YC22E?
A: Cathay CATHAYCOAT Yellow YC22E is a high-performance inorganic yellow pigment based on a stabilized complex of iron oxide and hydrated oxides, engineered for thermal and chemical stability in demanding industrial applications.
Q2: Is YC22E suitable for use in heat-sensitive polymer systems such as polyolefins or PVC?
A: Yes — YC22E exhibits excellent thermal stability and is widely used in polyolefin compounds, rigid and flexible PVC, and other thermoplastic and thermoset systems processed at elevated temperatures, without significant color shift or degradation.
Q3: How does YC22E perform under UV exposure and outdoor weathering conditions?
A: As an inorganic pigment, YC22E delivers outstanding lightfastness and weather resistance, maintaining color integrity and opacity over extended periods in exterior applications, including architectural coatings and automotive refinishes.
Q4: Can YC22E be dispersed using standard industrial milling equipment?
A: Yes — YC22E is designed for efficient dispersion in both aqueous and solvent-based systems using conventional high-speed dispersers, bead mills, or three-roll mills. Optimal dispersion typically requires formulation-specific wetting agents and shear optimization.
Q5: What types of binder systems is YC22E compatible with?
A: YC22E demonstrates broad compatibility across acrylics, alkyds, epoxies, polyurethanes, and chlorinated rubber binders, making it suitable for protective coatings, industrial finishes, and general-purpose paints.
