PERMABOND® ET5401 is a two-part, 2:1 mixable, semi- flexible toughened no slump epoxy adhesive with good adhesion to a variety of substrates such as wood, metal, ceramics and some plastics and composites. Permabond ET5401 forms tough bonds providing high peel resistance and high shear strength coupled with excellent resistance to high temperatures.
ET5401 performance is enhanced by curing at high temperature or being exposed to high temperature (such as during paint-stoving).\
