Q1: What is the primary chemical composition of CATHAYMAG Black MO4232?
A: CATHAYMAG Black MO4232 is a spinel-type mixed metal oxide pigment, predominantly based on iron and manganese oxides, engineered for high thermal stability and chemical inertness in demanding industrial applications.
Q2: Is this pigment suitable for use in high-temperature polymer processing, such as polypropylene or engineering thermoplastics?
A: Yes — MO4232 is specifically formulated to withstand processing temperatures up to 300°C and above, making it well-suited for coloration of polyolefins, polyesters, and other engineering plastics without significant thermal degradation or color shift.
Q3: How does MO4232 compare to carbon black in terms of UV stability and electrical conductivity?
A: Unlike carbon black, MO4232 is non-conductive and exhibits superior UV resistance without promoting polymer photo-oxidation. It delivers consistent jet-black hue under prolonged outdoor exposure while avoiding the conductivity-related limitations of carbon-based alternatives.
Q4: Can MO4232 be dispersed in aqueous systems for coatings or inks?
A: Yes — with appropriate surface treatment and dispersant selection, MO4232 achieves stable dispersion in both water-based and solvent-based systems. Its inorganic nature ensures compatibility across a broad pH range and resistance to hydrolysis.
Q5: What is the typical dosage range required to achieve full opacity and deep black shade in plastic compounds?
A: Dosage depends on formulation requirements and desired shade intensity, but MO4232 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — due to its high tinting strength and excellent hiding power.
