Product Benefits
  • D.E.R. ™ 721 is an aliphatic reactive diluent designed as modifier for other aromatic epoxy resin systems and can be blended with them in any ratio in order to tailor system performance.
  • The reactive diluent will significantly lower surface tension of standard aromatic liquid epoxy resins which will 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.
