Catonium ETPI (Ethyltriphenylphosphonium Iodide) is a white to offwhite crystalline powder, its chemical formula is C20H20P. ETPI is a quaternary phosphonium salt mainly used for the advancement and / or curing of phenolic based epoxy resins and thermosetting powder coatings. It can also be used in organic synthesis as a wittig reagent and as a phase transfer catalyst in the production of fluoroelastomers . This material is highly soluble in water and polarizable solvents. Ethyltriphnylphosphonium Iodide is also known as ETPI, ETPPI and TPEPI. Compared to amines, imidazoles and quaternary ammonium salts CatOnium ETPI features considerable better latency and thermal stability. Further it offers a low odor, minimal color formation and controlled reactivity. It decreases or eliminates side reactions and creates longer, straighter chain epoxy molecules which have a sharp molecular weight distribution.
