Liquid epoxy resin-based products, if they have gotten too cold or too old, may crystallize, harden, and turn white in the container. System Three® two-part products are formulated to resist crystallization, but it can still occur. Crystallization does not damage the resin in any way and are Typically recovered in one of two ways:
1) Heating in a water bath at 125°F or above until the resin clears up.
2) Heating in a microwave 10 seconds at a time until the resin clears up.
Make sure the crystals or cloudiness is completely gone, or the product can recrystallize in a short period. Allow the resin to return to room temperature before use.
NOTE: Hardeners (curing agents or Part B) will not crystallize but may darken over time. This color change will not affect their performance.
