Q1: What is the primary chemical composition of CATHAYCOAT Black BB33?
A: CATHAYCOAT Black BB33 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 BB33 suitable for high-temperature coating systems such as coil coatings or powder coatings?
A: Yes — BB33 is specifically formulated to retain color integrity and dispersion stability at elevated processing and curing temperatures, making it well-suited for coil coatings, architectural powder coatings, and other thermally robust systems.
Q3: How does BB33 compare to carbon black in terms of UV resistance and weathering performance?
A: As an inorganic oxide pigment, BB33 offers inherently superior UV stability and resistance to chalking or fading compared to organic or carbon-based blacks, especially in exterior-exposed coatings and plastics.
Q4: What types of resin systems is BB33 compatible with?
A: BB33 demonstrates broad compatibility with common industrial resin systems including acrylics, polyesters, epoxies, polyurethanes, and vinyls — both in solvent-borne and water-borne formulations.
Q5: What is the typical dosage range for BB33 in coating formulations?
A: Dosage depends on the desired opacity, color strength, and application method, but BB33 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in finished coatings.
