The ideal temperature for conservation: For the resin– hardener components: the suggested way to conserve is to store the resin and hardener in its original packaging, closed tightly at a temperature between 15°C and 25°C/59°F and 77°F. Excellent Casting surface. In most cases the ambient temperature is the air temperature unless the epoxy is applied to a surface with a different temperature. High temperature epoxy resins are often used for applications that go through heat cycles, or where composites will be exposed to elevated temperatures for extended periods of time. This material is economical, impact resistant, and provides a good moisture barrier. Low Temperature Epoxy Resin? I am getting involved in a boat building project during this winter (in Scotland). com MORTAR SYSTEMS where chemical resistant performance is required. There's some shade but it'll get sun exposure from mornings til noon.
