Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YA22ELV?
A: YA22ELV is a high-performance inorganic yellow pigment based on modified iron oxide and complex metal oxide chemistry, engineered for enhanced thermal stability and UV resistance. Its exact formulation is proprietary, but it contains no heavy metals such as lead, cadmium, or chromium(VI).
Q2: Is YA22ELV suitable for use in high-temperature polymer processing applications?
A: Yes — YA22ELV is specifically developed for demanding thermal environments and demonstrates excellent stability during extrusion and injection molding of engineering thermoplastics, including polypropylene, polyethylene, and certain polyesters, without significant color shift or degradation.
Q3: How does YA22ELV compare to organic yellow pigments in terms of weathering performance?
A: As an inorganic pigment, YA22ELV offers significantly superior lightfastness, chalk resistance, and long-term outdoor durability compared to most organic yellows—making it preferred for exterior architectural coatings, automotive refinishes, and industrial maintenance paints where color retention is critical.
Q4: Can YA22ELV be dispersed in water-based systems without surface treatment issues?
A: Yes — YA22ELV is supplied with a tailored inorganic surface treatment that promotes stable dispersion in both water-based architectural paints and aqueous industrial coatings, minimizing flocculation and supporting good gloss and tinting strength.
