Re: Stus-List West System Epoxy & resin
Hi Danny If the resin comes out milky you need to warm it up to de-crystalize it. A bucket of very hot water will do the trick nicely, plop the can into it and let it sit a half hour.

Re: Stus-List West System Epoxy & resin
BTW, here at the transformer factory we commonly store epoxies in the freezer to extend the shelf life. Some of our exotic very high temp epoxies (use in aircraft propulsion) are shipped and stored at -40C. We have been using warm water to eliminate the crystals in epoxy hardener since 1972.

Re: Stus-List West System Epoxy & resin
From the West website: Store at room temperature. Keep containers closed to prevent contamination. With proper storage, resin and hardeners should remain usable for many years. 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 resin to 125°F and stir to dissolve crystals. Hardeners may darken with age, but physical properties are not affected by color. After a long storage, verify the metering accuracy of the pumps and mix a small test batch to assure proper curing.
