Cured epoxies will soften when exposed to heat, but never melt. The terms "softening point,""heat deflection temperature," and "glass transition temperature(Tg)", are often used interchangeably. Our room-temperature curing epoxies will soften in a temperature range from 120-140°F. Please refer to the specific product Technical Data Sheet for details on these, and other, physical properties.
When cooled back down, the cured epoxy will return to its original hardness. Depending on the intended use and service, exposing the product to heat or heated objects, might or might not make a difference.
