Taffy process epoxy
WebSoHd epoxy resins can be prepared by the taffy process or the advancement process. Taffy Process. Bisphenol A reacts direcdy with epichlorohydrin in the presence of a … Webprocess will determine many properties of the cured epoxy resin, like, its adhesion to other materials, durability, resistance and versatility. The ratios of BPA and ECH also contribute to determine the epoxy’s final properties. Residual BPA content: Epoxy can be used either in solid (SsER) or liquid (LER) form depending on the applications.
