High peel strength adhesive
Because adhesive bonds have traditionally been strong in shear but weak in peel strength, many design engineers have found this feature limits their use when joining composite or aluminium structures
.
According to adhesive manufacturing specialist firm, Permabond, it has developed and patented a new epoxy adhesive, E3334, that it says achieves peel strengths on composite and aluminium substrates superior to any other adhesive in its class.
Permabond E3334 has excellent flow characteristics, which make it ideal for bonding sheets of dissimilar materials to form composite laminates. Its high peel strength allows the laminates to be pressed and formed after bonding without degradation of the bond.
E3334 is a two-component adhesive that cures at room temperature enabling large structures to be bonded together. External heating may be used to accelerate curing time for faster production of smaller items. Typical applications include the manufacture of composites for truck, bus, marine and commercial airline interiors as well as numerous specialist construction and assembly applications where high peel strength is critical.
