Product Description Product Name Hermcol® Transparent Brown Iron Oxide C.I. No Pigment Red 101, Pigment Yellow 42, Pigment Black 11 CAS No 1309-37-1, 51274-00-1, 12227-89-3 EINECS No. 215-168-2, 257-098-5, 235-442-5 Molecular Formula Fe2O3+Fe2O3·H2O+Fe3O4 Features Transparent brown iron oxide pigment exhibits high levels of transparency and color strength. It is acid-resistant and alkaline-resistant, non-bleeding, non-migratory and very stable. Transparent iron oxide pigments are extremely small particle sized iron oxide pigments. In order to be suitable for different systems, we offer general grade, long oil alkyd grade and water-based grade transparent iron oxide pigment dispersion.  Application Transparent brown iron oxide pigment can be applied in wood coatings, furniture finishes, automobile coatings, plastic coatings, metal coatings, architectural coatings, artist colors and high temperature glass ink. It can also be used in combination with organic pigments which can not only enrich the color and improve the chroma, but also can significantly improve the condition of poor weather resistance when organic pigments are used alone. Package 25kgs or 20kgs per paper bag/drum/carton. *Customized packaging available on request.
