Q1: What is the primary chemical composition of CATHAYCOAT Yellow YA23LV?
A: CATHAYCOAT Yellow YA23LV is a high-performance inorganic yellow pigment based on a modified lead-free chromate-free complex oxide system, engineered for thermal and chemical stability in demanding industrial coatings.
Q2: Is YA23LV suitable for use in high-temperature curing systems, such as powder coatings or coil coatings?
A: Yes — YA23LV exhibits excellent thermal stability and retains its color integrity and dispersion performance under typical industrial baking conditions up to 220°C, making it well-suited for powder coatings, coil coatings, and other thermoset systems.
Q3: How does YA23LV perform in terms of lightfastness and weather resistance compared to organic yellows?
A: As an inorganic pigment, YA23LV delivers significantly superior lightfastness, UV resistance, and long-term color retention versus conventional organic yellow pigments — particularly important for exterior architectural and automotive OEM applications.
Q4: Can YA23LV be used in water-based coating systems without compromising dispersion or stability?
A: Yes — YA23LV is surface-treated to ensure good compatibility and stable dispersion in both solvent-borne and water-based industrial coating formulations, including acrylic and polyurethane dispersions.
Q5: What is the typical dosage range for optimal color strength and opacity in industrial coatings?
A: Dosage depends on formulation requirements and desired shade intensity, but YA23LV is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — due to its high tinting strength and efficient hiding power.
