Anwendungen & Verwendung
Verwenden
Ethyltriphenylphosphonium acetate is mainly used to advance and cure phenolic-based epoxy resins and as a phase transfer catalyst. It exhibits considerably better latency and thermal stability when compared to amines, imidazoles and quaternary ammonium salts. Furthermore, it has minimal odour, colour formation, and controlled reactivity. It decreases or eliminates side reactions and creates longer, straighter chain epoxy molecules with sharp molecular weight distribution.
