04 · Handling and storage
Storing and handling 2,2-dimethyltrimethylene…
Storage conditions
The effectiveness of phenolic inhibitors is dependent on the presence of oxygen and the monomers must be stored under air rather than an inert atmosphere. Temp must be kept low to minimize formation of peroxides and other products. ... The acrylic esters may be stored in mild or stainless steel, or aluminum. /Acrylic acid & derivatives/
