Recommended Storage

DRUMS:­ Store at temperatures  below  25 o C. Storage life decreases with increasing storage temperature. Avoid exposure to heat  sources,  such as  direct sunlight  or steam pipes. Keep containers sealed to prevent moisture pickup and monomer loss.  Rotate stock.

BULK: ­ Store in  stainless  steel  tanks  or tanks  lined with epoxy  or phenolic  coatings.  Observe precautions against heat and moisture (see above).  An oxygen or dry air spurge may be desirable to keep inhibitors activated. Store at temperature below 25 ºC.
