Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YC23?
A: Cathay CATHAYCOAT Yellow YC23 is a high-performance inorganic yellow pigment based on a modified complex metal oxide system, engineered for enhanced thermal stability and lightfastness. It does not contain cadmium, lead, or chromium(VI), aligning with modern regulatory expectations for sustainable industrial pigments.
Q2: Is YC23 suitable for high-temperature processing applications such as engineering plastics or powder coatings?
A: Yes — YC23 is specifically formulated for excellent thermal stability, retaining its chromatic integrity during extrusion, injection molding, and curing processes commonly encountered in engineering thermoplastics (e.g., polyamide, PBT) and thermoset powder coatings.
Q3: How does YC23 perform in weather-exposed applications like exterior architectural coatings?
A: YC23 demonstrates strong resistance to UV radiation and atmospheric degradation, making it well-suited for durable exterior coatings where long-term color retention and minimal chalking are required. Its inorganic nature contributes to superior weatherability compared to many organic alternatives.
Q4: Can YC23 be used in water-based coating systems without compromising dispersion stability or tinting strength?
A: Yes — when properly dispersed using standard surfactants or polymeric dispersants, YC23 achieves uniform distribution and maintains high tinting strength in both solvent-borne and water-based architectural and industrial coating formulations.
