Q1: What is the primary chemical composition of CATHAYCOAT Black BA36?
A: CATHAYCOAT Black BA36 is a high-performance inorganic black pigment based on a stabilized mixed-metal oxide system, engineered for thermal and chemical stability in demanding coating applications.
Q2: Is BA36 suitable for high-temperature curing processes?
A: Yes — BA36 exhibits excellent thermal stability and retains its color integrity and dispersion characteristics during standard industrial baking cycles, including those exceeding 200 °C for short durations.
Q3: How does BA36 compare to carbon black in terms of UV resistance and weathering performance?
A: As an inorganic oxide pigment, BA36 offers inherently superior UV stability and resistance to chalking or fading compared to organic or carbon-based blacks, making it well-suited for long-term exterior exposure in architectural and industrial coatings.
Q4: What types of binder systems is BA36 typically compatible with?
A: BA36 demonstrates broad compatibility with common industrial coating resins, including epoxy, polyester, acrylic, and polyurethane systems — both solvent-borne and water-borne formulations.
Q5: What is the typical dosage range for achieving optimal blackness and opacity?
A: Dosage depends on formulation requirements and desired opacity, but BA36 is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight in the final coating system.
