DESCRIPTION: DEX-121 is a high purity liquid epoxy resin produced from bisphenol A and epichlorohydrin. Its high purity and low polymer fractions content ensures uniform performance with exceptionally low viscosity, low chloride content and light color. It provides improved elevated temperature properties under some cure conditions. DEX-121 can be cured using cycloaliphatic polyamines, polyamides, amidoamines, and a wide variety of curing agents. Although it might crystallize, this reversible physical phenomena can be greatly avoided by storing the resin at temperatures not below 25ºC.
