Storage
Drums - Store at temperatures below 25°ºC (77°F). Storage life decreases with increasing storagetemperature. Avoid exposure to heat sources such as direct sunlight or steam pipes. To avoidcontamination of product with water, do not store outdoors. Keep sealed to prevent moisture pick-up andmonomer loss. Mild mixing is recommended after prolonged storage. Rotate stock.
