Heat Deflection & Temperature Resistance

The heat deflection of a resin is the temperature at which the resin would start to distort and become softer. Once returned to room temperature the resin would set again in whatever shape it has been left in. For example, if a mug cast from Alumilite Amazing Clear Cast Epoxy Resin was brought up to 54 degrees C and an indent made and held whilst the resin returned to room temperature this would then remain imprinted. The heat deflection of each resin varies slightly but they are all in the same ball park. You can find this information on the product page or the Technical Data sheets at the bottom of the product descriptions.

The temperature resistance of a resin is a temperature that the resin would be not be able to take on a consistent basis, and at these temperatures you are very likely to permanently damage the resin.

The time that the resin is exposed to any temperature is a factor in how it will react.
