  • applications
    Water Treatment

    DEHA is used in water treatment chemical formulations for controlling corrosion in boilers very effectively due to its property of oxygen scavenging. It scores over conventional hydrazine hydrate since it is far less toxic and meets the standards for disposal of blow offs.

  • applications

    DEHA's powerful free radical scavenging ability coupled with its moderate volatility and relatively low order of acute toxicity makes it an ideal “Popcorn Polymer”/ vapor phase inhibitor for olefins or styrene monomer storage & recovery system.

  • applications
    Photographic Chemicals

    DEHA has reducing property, so it is used as an auxiliary chemical photographic developer for instant color photos. Also, DEHA is effective in stabilization of image and in the prevention of discoloration.

  • applications

    Phenol and phenolic antioxidants can be decolorised with DEHA.

  • applications

    DEHA is used as a color stabilizer.

  • applications
    Silicon Rubber

    DEHA can be used as a raw material for the hardener of the silicon sealant and coating agent.


  • Can be stored and handled in equipment made of stainless steel of Type SS304 or SS316 or steel lined with glass, polypropylene or polyethylene.
  • Storage in mild steel equipment or containers is not recommended.
  • DEHA drums should be stored in a cool and well ventilated area, away from sources of ignition.

Health & Safety

  • DEHA is irritating to skin, eyes and the mucous membrane.
  • In case of contact, the affected area should be washed with plenty of water for at least 15 minutes.
  • In case of inhalation, victims should be moved to fresh air and oxygen should be administered.
  • In case of ingestion, victims should be made to consume copious quantities of milk and water. Medical advice should be sought at once.
  • Personal protective equipment should always be used while handling.
