QUICK LINKS

Ethyltriphenylphosphonium acetate is mainly used for the advancement and curing of phenolic based epoxy resins and as a phase transfer catalyst. It exhibits considerable better latency and thermal stability when compared to amines, imidazoles and quaternary ammonium salts. Furthermore, it has minimal odor, and color formation, as well as, controlled reactivity. It decreases or eliminates side reactions and creates longer, straighter chain epoxy molecules which have a sharp molecular weight distribution.
