26/8/2021· Epoxy Temperature Limits. Your basic DIY epoxy can withstand low amounts of heat, but anything between 20°C to 90°C (68 -195 Fahrenheit) will begin to cause a change in the molecular structure and the epoxy will soften and cause distortion. This means the epoxy will become something like rubber and lose its hard glass-like texture.
