Q1: What is the primary chemical composition of CATHAYCOAT r PR112?
A: CATHAYCOAT r PR112 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 pigment use.
Q2: Is CATHAYCOAT r PR112 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 PR112 perform under UV exposure and weathering?
A: As an inorganic oxide-based pigment, PR112 exhibits outstanding UV stability and resistance to chalking or fading. It delivers long-term color retention in exterior architectural coatings, coil coatings, and other outdoor applications without requiring additional UV stabilizers in most formulations.
Q4: Can CATHAYCOAT r PR112 be dispersed in water-based systems?
A: Yes — PR112 is compatible with both water-based and solvent-based coating systems. For optimal dispersion in aqueous media, standard wetting agents and dispersants commonly used for inorganic pigments are recommended; pre-treatment or surface modification is not required.
Q5: What safety and handling precautions should be observed during processing?
A: As with all fine inorganic powders, appropriate engineering controls (e.g., local exhaust ventilation) and personal protective equipment (e.g., NIOSH-approved respirators for dust) are recommended during dry handling to minimize inhalation exposure. The material is non-volatile and non-flammable, and presents low acute toxicity when handled according to standard industrial hygiene practices.
