Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YS23E?
A: YS23E is a high-performance inorganic yellow pigment based on modified complex metal oxides, engineered for thermal stability and chemical resistance. Its exact composition is proprietary, but it contains no heavy metals regulated under RoHS or REACH SVHC candidate lists.
Q2: Is YS23E suitable for high-temperature processing applications such as powder coating or engineering plastics?
A: Yes — YS23E is specifically formulated for excellent thermal stability, maintaining color integrity and dispersion performance at temperatures commonly encountered in powder coating curing cycles and melt-processing of engineering thermoplastics.
Q3: How does YS23E compare to organic yellow pigments in terms of weathering resistance?
A: As an inorganic pigment, YS23E offers significantly superior UV stability and long-term outdoor durability compared to most organic yellows, making it preferred for exterior architectural coatings and automotive refinish systems where color retention is critical.
Q4: What is the typical dosage range when incorporating YS23E into solvent-based industrial coatings?
A: Dosage depends on desired opacity and chroma, but YS23E is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in the final formulation — due to its high tinting strength and efficient dispersion characteristics.
Q5: Can YS23E be used in waterborne systems without compromising stability or gloss?
A: Yes — YS23E is compatible with properly stabilized waterborne acrylic and polyurethane dispersions. When pre-dispersed using recommended surfactants and milling protocols, it delivers consistent color development and maintains film clarity and gloss in high-performance aqueous coatings.
