Storage & Handling

Storage and Shelf Life Information

In order to maintain the high degree of purity with which Ethyleneamine EA-300 is manufactured and shipped, the following storage and handling considerations are recommended:


Dry Inert Gas Blanket :

  • This product should be stored under a dry inert gas blanket, such as nitrogen, to minimize contamination resulting from contact with air and water.


Materials of Construction :

  • If slight coloration of the ethyleneamine is acceptable, storage tanks may be made of carbon steel or black iron, provided they are free of rust and mill scale.
  • However, if the amine is stored in such tanks, color may develop due to iron contamination.
  • If iron contamination cannot be tolerated, tanks constructed of types 304 or 316 stainless steel should be used.
  • Note: Because they are quickly corroded by amines, do not use copper, copper alloys, brass, or bronze in tanks or lines.
  • Recommended storage construction for EA-300 is stainless steel or carbon steel.


Storage Temperature :

  • Ethyleneamine EA-300 has a pour point of -21°C. To avoid freezing, the product should be maintained above this temperature.
  • At temperatures below 5°C, viscosity becomes so high that the product cannot be easily pumped.

Shelf Life :

  • The product should retain its conformance to sales specifications for a period of at least two years from date of manufacture if the product is stored at less than 100°F (37.8°C) in its undamaged, unopened, factory packaged container.
