Q1: What is the primary chemical composition of CATHAYCOAT Brown BRC86?
A: CATHAYCOAT Brown BRC86 is a mixed-metal oxide pigment based predominantly on iron and manganese oxides, engineered for thermal and chemical stability in demanding industrial coating systems.
Q2: Is BRC86 suitable for high-temperature curing applications, such as coil coatings or powder coatings?
A: Yes — BRC86 exhibits excellent thermal stability and retains its color integrity during standard industrial baking cycles up to 250 °C, making it well-suited for coil coatings, automotive refinishing primers, and thermoset powder formulations.
Q3: How does BRC86 perform in UV-exposed exterior applications?
A: As an inorganic pigment, BRC86 offers inherently high UV resistance and minimal fading under prolonged outdoor exposure, supporting long-term color retention in architectural and industrial maintenance coatings.
Q4: Can BRC86 be used in water-based coating systems without dispersion or compatibility issues?
A: Yes — BRC86 is surface-treated for enhanced wetting and stabilization in aqueous media, enabling robust performance in acrylic, PUD, and hybrid waterborne industrial coatings when properly dispersed using standard high-shear methods.
Q5: What is the typical dosage range for achieving optimal color strength and opacity?
A: Dosage depends on formulation requirements, but BRC86 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — to achieve strong brown coloration and effective hiding power across diverse resin systems.
