Q1: What is the primary chemical composition of CATHAYMAG Black MO1105?
A: CATHAYMAG Black MO1105 is a high-performance inorganic black pigment based on a complex metal oxide system, engineered for thermal and chemical stability. It does not contain elemental carbon or organic dyes, distinguishing it from carbon blacks and organic pigments.
Q2: Is this pigment suitable for use in heat-sensitive polymer systems such as polyolefins or engineering thermoplastics?
A: Yes — MO1105 is specifically formulated for excellent thermal stability and is routinely processed in polymers requiring melt temperatures up to 300 °C, including PP, PE, ABS, and polyesters. Its inorganic nature ensures minimal degradation or color shift during extrusion or injection molding.
Q3: How does MO1105 compare to carbon black in terms of UV resistance and weathering performance?
A: Unlike carbon black, which can promote polymer photo-oxidation under prolonged UV exposure, MO1105 exhibits inherently low catalytic activity and delivers superior long-term color retention and matrix stability in outdoor applications — especially where UV resistance and non-blooming behavior are critical.
Q4: Can MO1105 be used in food-contact compliant compounds?
A: MO1105 is designed for industrial and functional coloration applications. While its inorganic composition supports favorable toxicological profiles, formal food-contact compliance depends on final compound formulation, processing conditions, and regional regulatory evaluation — users should consult their regulatory team and conduct appropriate migration testing as needed.
Q5: What dispersion methods are recommended for optimal performance in liquid systems?
A: For coatings, inks, or liquid masterbatches, MO1105 responds well to high-shear dispersion using conventional media mills or bead mills. Pre-wetting with compatible solvents or resins prior to grinding enhances deagglomeration and helps achieve uniform particle distribution and maximum blackness intensity.
