Q1: What is the primary chemical composition of Cathay FERROTINT Green F18G?
A: Cathay FERROTINT Green F18G is a high-performance inorganic green pigment based on a stabilized iron oxide–chromium oxide spinel structure, engineered for thermal and chemical stability without soluble heavy metals.
Q2: Is this pigment suitable for use in polyolefin compounds processed at high temperatures?
A: Yes — F18G exhibits excellent thermal stability and retains its color integrity during extrusion and injection molding of polypropylene and polyethylene, typically up to 300°C for short residence times.
Q3: How does F18G compare to organic green pigments in terms of weather resistance?
A: As an inorganic spinel pigment, F18G offers significantly superior UV resistance, chalking resistance, and long-term color retention compared to most organic greens—making it preferred for outdoor applications such as architectural coatings and agricultural films.
Q4: Can F18G be used in water-based coating systems?
A: Yes — when properly surface-treated, F18G demonstrates good dispersibility and stability in aqueous acrylic, epoxy, and alkyd emulsions, supporting consistent tinting and minimal settling in formulated paints and industrial coatings.
Q5: What is the typical dosage range for achieving full opacity in plastic applications?
A: Dosage depends on the base polymer, desired shade depth, and processing method, but F18G generally achieves effective opacity at concentrations ranging from 0.1% to 2% by weight in most thermoplastics.
