04 · Handling and storage
Storing and handling 2-Hydroxyethyl Methacrylate
Storage conditions
Temp during storage must be kept low to minimize formation of peroxides and other oxidation products. ... Storage temp below 30 °C are recommended for the polyfunctional methacrylates. ... The methacrylate monomers should not be stored for longer than one year. Shorter storage times are recommended for the aminomethacrylates, ie, three months, and the polyfunctional methacrylates, ie, six months. Many of these cmpd are sensitive to UV light and should, therefore, be stored in the dark. The methacrylic esters may be stored in mild steel, stainless steel, or aluminum. /Methacrylic acid & derivatives/
