Permabond launches high temperature epoxy adhesive
Permabond ET5401 has been developed to bond a wide variety of engineering materials, such as composites, thermoplastics, metals and ceramic materials. Permabond believes this product will be ideal for the composites bonding industry, the transportation market and automotive industries.
Traditionally, standard two-component epoxy adhesives (resin and hardener) can only resist temperatures of up to around 80°C before they soften, resulting in joint failure, reports Permabond. The new Permabond ET5401 epoxy adhesive can successfully survive 140°C continuously, and maintain its performance characteristics.
The adhesive can be exposed to temperatures higher than this (such as those experienced in a paint stoving oven) for short periods, providing the adhesive is not overly stressed, Permabond notes.
Permabond ET5401 is a toughened product which is ideal for bonding dissimilar materials (such as metal to composite) where differential thermal expansion and contraction could be an issue. It is also ideal for applications where good impact and vibration resistance is important.
