04 · Handling and storage
Storing and handling Hexamethylene diacrylate
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. Moisture may cause rust-initiated polymerization. /Acrylic acid & derivatives/

Reactivity
1,6-HEXANEDIOL DIACRYLATE is temperature sensitive (NTP, 1992). May react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen. Can undergo very exothermic addition polymerization reactions. May undergo autoxidation upon exposure to the air to form explosive peroxides.
