D.E.R.® 750

• D.E.R.® 750 Liquid Epoxy Resin is a low viscosity, dipropylene glycol diepoxide modified standard bisphenol-A based liquid epoxy resin.
• Typically, bisphenol-A-epichlorohydrin based epoxy resins and other di- or multi-functional resins, containing the aromatic ring structure, will cure to hard, rigid compositions having rather low impact and elongation characteristics.
• D.E.R.® 750 Epoxy Resin has been designed to impart flexibility to what may otherwise be rather brittle, epoxy binder systems.
• Its reduced viscosity versus standard liquid epoxy resins offers improved surface wetting and better adhesion.
• The reactive diluent increases pot life as well as flexibility and impact resistance. The reactive diluent limits the solvent resistance somewhat whereas an improved acid resistance can be observed when cured at room temperatures.
• A broad range of curing agents is available to cure this epoxy resin at ambient temperatures.
• Most frequently used are aliphatic and cycloaliphatic polyamines and modified versions of these. Elevated temperature cure is required to develop full end properties if anhydride or catalytic curing agents are employed.
• Used in combination with cycloaliphatic amine-epoxy adduct curing agents, binders can be formulated with improved elongation at break.
• The improved flexibility makes these formulations especially suitable for applications such as civil engineering compounds (crack bridging) or adhesives.
• In combination with anhydrides or amine curing agents and a suitable elevated temperature curing schedule, the toughness of fiber reinforced composites can be improved significantly.
