What is ArtResin's heat resistance?

  • What Is ArtResin's Heat Resistance?
  • The maximum temperature that cured ArtResin can tolerate is 120°F or 50°C.
  • At temperatures as high as that, the cured pieces may become a little flexible but once they cool off, they will harden up once again. Typically, the heat generated from a hot mug will not damage the resin surface on a coaster, but if your cured resin is exposed to temperatures beyond 120°F or 50°C, however - for example, you place a hot dish right out of the oven on a resined surface or you leave a cured piece in a hot car - it could cause irreparable damage.
