Once opened, the shelf life for TotalBoat ThickSet epoxy resin and hardener is approximately six months to one year, if stored under proper conditions. ThickSet should be stored at 60-90°F, in a dry place. Make sure containers are completely sealed, and store them on a raised surface off the floor during cold weather; avoid storing near outside walls or doors.
Crystallization may occur in epoxy resin or hardener that becomes contaminated with moisture or dust, or that is exposed to low temperatures. If the resin and/or hardener shows any sign of cyrtallization, don't use it until it has been liquefied, or returned to its original liquid state. To do this, place the closed container in a warm water bath and heat the material to 140°F-150°F. Maintain this temperature until all the crystals are gone and the material has returned to its liquid form.
