Q1: What is the primary chemical composition of CATHAYCOAT Black BB30?
A: CATHAYCOAT Black BB30 is a high-performance inorganic black pigment based on a stabilized mixed-metal oxide system, engineered for thermal and chemical stability in demanding industrial applications.
Q2: Is BB30 suitable for use in high-temperature coating systems such as coil coatings or powder coatings?
A: Yes — BB30 is specifically formulated to retain color integrity and dispersion stability at elevated processing and curing temperatures, making it well-suited for coil coatings, powder coatings, and other thermally robust coating systems.
Q3: How does BB30 compare to carbon black in terms of UV resistance and weathering performance?
A: As an inorganic oxide pigment, BB30 offers inherently superior UV stability and resistance to chalking or fading compared to organic or carbon-based blacks, especially in exterior architectural and industrial maintenance coatings.
Q4: What are the recommended dispersion methods for optimal performance in liquid coating systems?
A: For best results, BB30 should be dispersed using high-shear mixing or bead milling with compatible resin vehicles and standard dispersing additives; pre-wetting and gradual incorporation help achieve uniform distribution and maximize tinting strength.
Q5: Can BB30 be used in food-contact or pharmaceutical-grade coating applications?
A: BB30 is not certified for direct food-contact or pharmaceutical applications; it is intended for industrial, architectural, and protective coating uses where regulatory compliance is governed by general industrial safety standards.
