Unlike thermoplastic alternatives such as hot melt adhesives, cured thermosetting epoxies will not re-flow or melt when heated. Instead, epoxies will undergo a transition from a hard-rigid state to a more pliable, rubbery state. The temperature range during which this transition takes place is known as the glass transition temperature, T_g.

A majority of manufacturers, including Resin Designs, understands that new technology is frequently misunderstood. For example, let’s circle back to 15 years ago when suppliers of LEDs believed that this light source could cure UV adhesives more cost efficiently than mercury bulbs, metal-halide bulbs and electrodeless bulbs. Manufacturers also believed the following:
