D.E.R. 721 is an aliphatic reactive diluent (C12-C14 alkyl glycidyl ether) designed as modifier for other aromatic epoxy resin systems and can be blended with them in any ratio in order to tailor system performance.

  • Significantly lowers surface tension of standard aromatic liquid epoxy resins which results in excellent surface wetting, adhesion and lower viscosity at given filler loading
  • The aliphatic chain reactive diluent typically increases pot life as well as flexibility (impact resistance)
  • Although the reactive diluent limits the solvent resistance somewhat, acid resistance is improved.
