Storage 305 is hygroscopic and absorption of moisture would affect polyol reactivity and physical properties of resulting polymer. The material should be stored in sealed containers and in dry conditions, away from direct sources of heat. The recommended storage temperature is between 20~35. Opened drums must be reclosed tightly immediately after drawing-off material.
Shelf Life 12 months from production date.
