Cloudy Epoxy - before using

Epoxy resins under certain conditions can become solid or have a slush like appearance. This is called crystallization and it is where some component parts of the epoxy resin form a crystal like structure. Crystallization appears in the form of cloudiness, free-floating crystals. crystal masses or as completely solidified. Crystallization of epoxy resins is completely reversible just like the freeze/thaw cycles of ice and water. As water remains unchanged from repeated cycles, so do the original properties of epoxy resin. To reverse simply heat to 65 deg C until epoxies return to clear. immerse jugs in very hot water or water bath. Milky resin (which looks cloudy) can also happen when your resin is full of a lot of many tiny microbubbles that it makes.
