Q1: What is the primary chemical composition of CATHAYGRAN Brown F8860GS?
A: CATHAYGRAN Brown F8860GS 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 polyolefin compounds exposed to high processing temperatures?
A: Yes — F8860GS exhibits excellent thermal stability and is routinely used in polypropylene and polyethylene masterbatches processed at temperatures up to 280 °C without significant color shift or degradation.
Q3: How does F8860GS perform under UV exposure and outdoor weathering conditions?
A: As an inorganic oxide pigment, it delivers outstanding UV resistance and long-term weatherability, making it well-suited for exterior-grade plastics, coatings, and construction materials.
Q4: Can F8860GS be dispersed effectively in water-based systems?
A: While primarily optimized for polymer melt compounding and solvent-based coatings, it can be formulated into stable aqueous dispersions using appropriate surfactants and milling protocols — compatibility should be verified in the target system.
Q5: What is the typical dosage range when incorporating F8860GS into plastic masterbatches?
A: Dosage depends on the desired shade intensity and base resin, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight in final compounded products.
