Panoramica

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.
