Processing Information
  • A layer of adhesive 0.002 in. to 0.004 inches (0.05 mm to 0.10 mm) thick will normally impart the greatest lap shear strength to a joint.
  • Joint components should be assembled and clamped as soon as the adhesive has been applied.
  • Even contact throughout suffices to ensure proper cure.
Product Applications
  • Ski and snowboard lamination
  • Archery limb lamination
  • Honeycomb core facing

Technical Details & Test Data

Typical Physical Properties

Unless a different test is specified, the figures given below were determined by testing standard specimens made up by lap-jointing 4-inch x 1-inch x 0.06-inch (10-cm x 2.5-cm x 1.5-mm) strips of aluminum. The joint area was 0.5 inch x 1 inch (12.5 mm x 2.5 cm) in each case. Samples were tested at 77°F (25°C) and cured for 7 days at 77°F (25°C) unless otherwise noted. Property Condition
