Netheads, There was an inquiry a few weeks ago about the Storage/Shelf life of Resins.
I have just received the Product Guide for the West System Store at room temperature. Keep containers closed to prevent contamination. With proper storage, resin & hardener should remain usable for many years. Over time 105 resin will thicken slightly & therefore require extra care when mixing. hardeners may darken with age, but physical properties are not affected by colour. Mini Pumps may be left in containers during storage. After a long storage, it is a good idea to verify the metering accuracy of the pumps & mix a small test batch to assure proper curing. Repeated Freeze/thaw cycles during storage may cause the crystallization of 105 Resin. Warm resin to 125 degrees F & stir to dissolve crystals. Don't forget this only applies to the West System, but may be a guide for other types. I hope this gives some guide to those who were not sure where to store the resin, or how long it will last . But as always irrespective of age etc do a test piece your life depends on it & you will sleep better at night knowing you have done all you could. Robin [email protected]
