New BUILDERA Service Note SN-2018-1 Epoxy Resin Crystallization

How to Restore Crystallized Epoxy Resin Due to Transportation or Cold Exposure


Two-part epoxies—such as those used to install structural crack monitors—are subject to reversible crystallization when exposed to cold temperatures or temperature cycling during transit or storage. Crystallized epoxy resin may become partly-to-fully solid, making it difficult to dispense with reasonable plunger pressure.

This Buildera service note includes a simple heating procedure for end-users to effectively reverse crystallization, restoring the epoxy to original factory conditions. Instructions are laboratory tested for 30 ml two-part Buildera STRUPOXY (Aboweld 8101-5), however a similar heating procedure may be used with any epoxy subject to crystallization during storage or cold exposure.
