An epoxy resin’s physical property such as its viscosity and cure reaction is influenced by temperature. During shipping or after prolonged storage, especially after the winter season, the package can be exposed to temperatures below 50ºF and may crystallize the resin component (PART A). The crystallized resin will appear as a white mass on the bottom of the bottle or the entire bottle is solid. Do not throw away or use until the PART A RESIN has been melted back to its liquid phase.
Warm the resin by placing the entire bottle in a hot water bath set at 120°F to 150°F.
The crystallized resin will melt back to a clear liquid. Allow the resin to cool back to 75°F to 80°F maximum before adding the curing agent.
