So, set the oven to the lowest possible temperature (65 C, 150 F). UV resin requires no mixing but is more costly than epoxy resin in terms of volume. A good rule of thumb is using the same amount of hardener to the same amount of resin use. Heat Curing Epoxy Resin is Similar to Baking a Cake To make the heat curing process even easier to understand, let's look at the example of a cake.

Use a hot air gun, heat lamp, or other heat sources to warm the resin and hardener before mixing or after the epoxy is applied. The wonders of epoxy are clear to those who deal with it on a regular basis. Latent hardeners are mixed into the epoxy resin and have very limited . Room temperature: The best temperature for the resin to cure fully is 75°F to 85°F (25°C to 30°C). Single part epoxies contain both resin and hardener in the one mixture (unlike 2 part epoxies where they are packaged separate and mixed before use). Answer: Epoxy should work entirely fine for that purpose. Yet amid all benefits of epoxy resins, there is the unavoidable fact that epoxy isn't easy to work with. So, set the oven to the lowest possible temperature (65 C, 150 F).
