Epoxy latent curing agent
WebFeb 5, 2024 · Developing latent curing agents from bioresources are of great significance to the sustainable development of epoxy resins. In this work, a bio-based latent curing agent--phytate salt PAIM--was prepared by a simple salt-forming reaction between imidazole and naturally occurring phytic acid, and was mixed with commercial bisphenol … WebThey function as a latent curing agent by essentially blocking the free primary amine until exposed to moisture in the air. Existence of a possible tautomer with active N-H groups could provide some reactivity prior to hydrolysis, but the generally accepted belief attributes the predominant curing mechanism to the free amine.
