Application Areas

Water Treatment: DEHA is used in water treatment Chemical Formulations for controlling corrosion in boiler very effectively due to its property of oxygen scavenging. It scores over conventional hydrazine hydrate since it is far less toxic and meets the standard for disposal of blow offs without any difficulty giving a good protection against corrosion at the same time.

Polymerization: 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"/vapour phase inhibitor for olefins or styrene monomer storage & recovery system. Because of its capability of inhibiting polymerization in the gas phase, DEHA is finding use as an in-process inhibitor for the production of styrene, divinylbenzene, butadiene, isoprene and other monomers containing a reactive double bond. 

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

Decolorisation: Phenol and phenolic antioxidants can be decolourised with DEHA.

Inhibitors: DEHA also can be used as a colour stabilizer of monoalkyl phenol.

Silicon Rubber: DEHA can be used as a raw material of the hardener of the Sealant and coating agent.

Storage: DEHA can be stored and handled in equipment made up of type 304 or 316 stainless steel or steel lined with glass, polypropylene or polyethylene .Storage in mild steel is not recommended.

Packing:  25 & 180 kgs net weight in HDPE drums.

Health & Safety:  DEHA is combustible. It may cause irritation to eyes and skin. Wear goggles and gloves while handling. In case of contact with eye and skin affected area should be washed with plenty of water for at least 15 minutes and call a physician. Spills of DEHA may be flushed away with water applied quickly to the entire spill. Keep DEHA away from heat and open flames and the container should be closed when not in use. In case of fire, use water foam, dry chemical or CO2
