Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YC22C?
A: YC22C is a high-performance inorganic yellow pigment based on a modified complex metal oxide system, engineered for thermal and chemical stability. Its exact composition is proprietary, but it contains no heavy metals such as lead, cadmium, or chromium(VI), aligning with modern regulatory expectations for industrial coatings.
Q2: Is YC22C suitable for high-temperature curing applications, such as coil coating or powder coating?
A: Yes — YC22C is specifically formulated to retain color integrity and dispersion stability under elevated processing temperatures, typically up to 250°C. It demonstrates excellent resistance to thermal degradation during baking cycles common in coil and powder coating systems.
Q3: How does YC22C perform in UV-exposed outdoor applications?
A: As an inorganic pigment, YC22C offers inherently strong UV stability and weather resistance. When properly incorporated into durable resin systems (e.g., polyester, fluoropolymer, or silicone-modified acrylics), it delivers long-term color retention and minimal chalking in exterior architectural and industrial coatings.
Q4: Can YC22C be used in water-based coating systems?
A: Yes — YC22C is surface-treated to ensure good compatibility and stable dispersion in both solvent-based and water-based industrial coating formulations, including acrylic and polyurethane dispersions. Optimal performance requires appropriate dispersant selection and standard milling procedures.
Q5: What is the typical dosage range for YC22C in finished coating formulations?
A: Dosage depends on the required opacity, hue strength, and application method, but YC22C is generally used at low concentrations — typically ranging from 0.1% to 2% by weight of the total formulation — due to its high tinting strength and efficient light absorption characteristics.
