STORAGE
Drums - Store at temperatures below 25'C (77°F). Storage life decreases with increasing storage temperature. Avoioexposure to heat sources such as direct sunliaht or steam pipes, To avoid contamination of oroduct with water. donot store outdoors. Keep containers sealed to prevent moisture pick-up and monomer loss. Mild mixing isrecommended after prolonged storage. Rotate stock.
