Q1: What is the primary chemical composition of CATHAYCOAT r PR180?
A: CATHAYCOAT r PR180 is a high-performance inorganic pigment based on a stabilized mixed-metal oxide system, engineered for exceptional thermal and chemical resistance. Its exact composition is proprietary, but it contains no heavy metals of concern such as lead, cadmium, or mercury, and complies with global regulatory expectations for industrial pigments.
Q2: Is CATHAYCOAT r PR180 suitable for high-temperature coating applications?
A: Yes — this pigment is specifically formulated for demanding thermal environments. It maintains color stability and structural integrity in organic and inorganic coatings cured at temperatures up to 600 °C, making it well-suited for exhaust systems, industrial furnaces, and ceramic glazes.
Q3: How does CATHAYCOAT r PR180 perform under UV exposure and weathering?
A: As an inorganic oxide-based pigment, it exhibits outstanding UV stability and resistance to chalking, fading, and gloss loss in exterior applications. It is widely used in architectural coatings and infrastructure finishes where long-term color retention is critical.
Q4: Can CATHAYCOAT r PR180 be dispersed in both water-based and solvent-based systems?
A: Yes — it is compatible with a broad range of resin systems and dispersants. Successful incorporation typically requires high-shear dispersion and may benefit from surface treatment optimization depending on the vehicle chemistry. Formulators commonly achieve stable dispersions in epoxy, silicone, polyester, and acrylic binders.
