Storage & Handling:
In order to prevent polymerization, 2-Hydroxyethyl Acrylate (2-HEA) must always be stored under air, and never under inert gases. 
The presence of oxygen is required for the stabilizer to function effectively. 
It has to contain a stabilizer and the storage temperature must not exceed 35°C. 
Under these conditions, the storage stability of one year can be expected upon delivery. 
In order to minimize the likelihood of over storage, the storage procedure should strictly follow “first-in-first out” principle. 
For extended storage periods over 4 weeks it is advisable to replenish the dissolved oxygen content. Over time the content of Ethylene Glycol Diacrylate slowly increases. 
If this trace component is relevant to your process, the material should be consumed within the latest 6 months after receipt of the material. 
The preferred construction material for tanks and pipes is stainless steel. 
Carbon steel is also acceptable, although the formation of rust may be a problem with product quality (color). Iron(III)-ions have been shown to be a weak polymerization initiator. 
If carbon steel is to be used, special procedures should be used to prepare the tank for use. 
Storage tanks, pumps, and pipes should be earthed.
