Q1: What is the primary chemical composition of CATHAYCOAT Brown BRC88?
A: CATHAYCOAT Brown BRC88 is a mixed-metal oxide pigment based on iron and chromium oxides, engineered for thermal stability and UV resistance in demanding inorganic pigment applications.
Q2: Is BRC88 suitable for high-temperature coating systems such as ceramic or enamel glazes?
A: Yes — BRC88 exhibits excellent thermal stability and is commonly used in firing applications up to 1200°C, including porcelain enamels, ceramic colorants, and high-temperature industrial coatings.
Q3: How does BRC88 perform in acidic or alkaline environments?
A: As an inorganic oxide pigment, BRC88 demonstrates strong chemical inertness and maintains color integrity across a broad pH range, making it suitable for use in both acidic and alkaline binder systems.
Q4: Can BRC88 be dispersed in water-based systems without special surfactants?
A: While BRC88 is inherently hydrophobic, it can be effectively dispersed in aqueous media using standard dispersing agents or by pre-treatment with compatible wetting aids — formulation optimization is recommended for consistent rheology and stability.
