Pigment Red 101 (C.I. 77491) is an inorganic iron oxide pigment, commonly referred to as synthetic iron oxide red. It produces a reddish-brown to deep red shade and is widely used in coatings, construction materials, plastics, and other industrial coloration applications.
Pigment Red 101 is primarily composed of iron oxide (Fe₂O₃) produced through synthetic processes that provide controlled particle size and consistent color properties. Compared with natural iron oxide pigments, synthetic Pigment Red 101 typically offers more uniform color quality and stable performance.
Due to its inorganic composition, Pigment Red 101 is known for its excellent durability, chemical stability, and resistance to environmental conditions, making it suitable for both indoor and outdoor applications.
