How long does 2 part epoxy take to dry?

Full cure of a two part epoxy can be several days. However adequate strength for further assembly, or packaging can be reached within minutes or hours. To increase full cure speed, heat can be used. The general rule of thumb is for every 10C increase in temperature the cure time is cut in half.

How long should epoxy cure before sanding?

Epoxy cuts easiest after 24 hours of cure, but before 48 hours or more: it has cured enough to be cut, but has not reached full mechanical properties. Epoxy’s hardness dulls sandpaper fast. In addition, cured epoxy can quickly fill sandpaper, rendering it ineffective after several swipes.

How strong is 2 part epoxy?

Ultra high strength, two part epoxy adhesive that bonds well to most metals and plastics. Aluminum to aluminum lap shear strength exceeds 4,000 psi. T-peel strength >50 pli.
