Q1: What is the primary chemical composition of CATHAYMAG Brown MO2218?
A: CATHAYMAG Brown MO2218 is a mixed-metal oxide pigment based on iron and manganese oxides, engineered for thermal and chemical stability in demanding industrial applications.
Q2: Is this pigment suitable for use in high-temperature polymer processing, such as polypropylene or engineering thermoplastics?
A: Yes — MO2218 exhibits excellent thermal stability and is commonly used in polymers processed above 200 °C, including PP, PE, and certain engineering resins, without significant color shift or decomposition.
Q3: How does MO2218 perform under UV exposure and outdoor weathering conditions?
A: As an inorganic oxide pigment, MO2218 offers inherent UV resistance and long-term weathering stability, making it well-suited for exterior applications where color retention and durability are critical.
Q4: Can MO2218 be dispersed in aqueous systems, such as architectural coatings or water-based inks?
A: While primarily optimized for solvent-based and polymer systems, MO2218 can be formulated into aqueous dispersions using appropriate surfactants and milling techniques — performance depends on pH control and stabilization strategy.
Q5: What is the typical dosage range when incorporating MO2218 into plastic masterbatches?
A: Dosage generally ranges from 0.1% to 2% by weight depending on the desired shade intensity, base resin, and processing conditions — lower concentrations are often sufficient due to its strong tinting strength and opacity.
