Q1: What is the primary chemical composition of Cathay CATHAYCOAT Brown BRS86?
A: Cathay CATHAYCOAT Brown BRS86 is a high-performance inorganic pigment based on mixed metal oxides, formulated to deliver stable brown coloration with excellent thermal and chemical resistance. Its exact composition is proprietary, but it contains no heavy metals regulated under major global pigment safety frameworks.
Q2: Is this pigment suitable for use in heat-sensitive polymer systems such as polyolefins or PVC?
A: Yes — BRS86 is specifically engineered for high-temperature stability and demonstrates excellent dispersion and color retention during extrusion and injection molding of thermoplastics, including polypropylene, polyethylene, and rigid/flexible PVC.
Q3: How does BRS86 perform under UV exposure and outdoor weathering conditions?
A: As an inorganic oxide-based pigment, BRS86 offers inherently high UV stability and resistance to fading, chalking, or color shift when incorporated into exterior-grade coatings, plastics, or construction materials exposed to prolonged sunlight and humidity.
Q4: Can BRS86 be used in water-based coating systems?
A: Yes — with appropriate surface treatment and dispersion optimization, BRS86 is compatible with aqueous acrylic, epoxy, and polyurethane dispersions. Performance depends on pH control, rheology modifiers, and shear conditions during formulation.
