Shelf life foe the West Systems 105 system is as follows:

Store at room temperature. Keep containers closed to prevent contamination. With proper storage, resin and hardeners should remain usable for many years. After a long storage, verify the metering accuracy of the pumps. Mix a small test batch to assure proper curing.

Over time, 105 Resin will thicken slightly and will therefore require extra care when mixing. Repeated freeze/thaw cycles during storage may cause crystallization of 105 Resin. Warm the resin to 125°F and stir to dissolve crystals.

If you mix the hardener and resin you have a working time of 10-15 minutes for the fast and 30-40 minutes for the slow. The resin and hardener have a shelf life of 3 years.
