Permabond releases high temperature resistant structural epoxy adhesive
12 August 2011
Permabond Engineering Adhesives has introduced a high temperature resistant structural epoxy adhesive, dubbed ET5401, that will bond a wide variety of engineering materials such as composites, thermoplastics, metals and ceramic materials. Whereas, standard two-component epoxy adhesives resist temperatures of up to 80°C before they soften (resulting in joint failure), ET5401 can successfully survive 140°C continuously, and maintain its performance characteristics.
ET5401 can also be exposed to temperatures higher than this for short periods (such as those experienced in a paint stoving oven), providing the adhesive is not overly stressed. In fact, exposing the adhesive to such high temperatures actually increases the adhesive strength and long-term structural performance.
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.
