Once it's fully cured, TotalBoat TableTop Epoxy is a very stable and durable material.

If a bond failure or cracking occurs in extremely cold temperatures, the most likely cause is that the substrate contracted or expanded because of sudden temperature changes. 

If the cured TableTop Epoxy separates from the substrate when exposed to extremely cold temperatures, this is a sign of improper surface preparation before the epoxy was applied, or the epoxy was applied to a substrate to which it could not form a very strong bond.

Most of the time, in extremely cold temperatures, the substrate itself will crack, while the cured epoxy is still adhered to it.
