- Additional Information
- D.E.R.® 325 Liquid Epoxy Resin is a low viscosity, C12-C14 aliphatic glycidyl ether diluted standard bisphenol-A based liquid epoxy resin.
- Its surface tension is lower than other reactive diluent diluted epoxy resins and results in better surface wetting, better adhesion, and will have slightly lower viscosity at any given filler loading.
- The lower surface tension also results in better filler acceptance, reduced odor, lower vapor pressure, and less potential for handling hazards.
- The reactive diluent in this epoxy resin blend will increase the pot-life as well as the flexibility (impact resistance).
- The reactive diluent also limits the solvent resistance somewhat.
- D.E.R.® 325 Epoxy Resin offers improved acid resistance versus standard epoxy resins such as D.E.R.® 325 Liquid Epoxy Resin.
- A wide variety of curing agents is available to cure this liquid epoxy resin at ambient conditions.
- Most frequently used are cycloaliphatic polyamines, polyamides, amidoamines, and modified versions of these.
- Such systems are sometimes cured at elevated temperatures to improve selected properties such as chemical resistance and glass transition temperature.
- Elevated temperature cures are necessary and long post-cures are required to develop full end properties if anhydride or catalytic curing agents are employed.
- NOTE: D.E.R.® 325 Epoxy Resin might crystallize. This reversible physical phenomenon can be greatly avoided by storing the resin at temperatures not below 25°C. For further details see the technical bulletin, Crystallization of Liquid Epoxy Resins.
