• Heat resistant up to 120°C (248°F)
• Resists exposure to water and a wide variety of chemical including transformer oils and SF₆
• Gap filling and non-sagging up to 5mm thickness
• Bonds well to a wide variety of substrates used in electrical applications
• Can be used at temperatures up to 180°C (356°F) in accordance with UL testing

• Transformer Core Lamination Bonding for the Large Oil Filled Power Transformers and the Distributior Transformers including Dry Type Distribution Transformers.
• Bonding metals to polymeric insulation materials
• Bonding ceramics Producing electrical insulation and apparatus such as insuators, bushings, insulation for capacitance tap
• Mounting swichge components
• Manufacturing submersible electrical equipment for underground vaults

Application of Insulation Bonding Compound

• The resin/hardener mix is applied with a spatula to the pretreated and dry joint surfaces.
• A layer of adhesive 0.002 to 0.004-inches (0.05 to 0.10-mm) thick will impart the greatest lap shear strength to a joint.
• The joint components should be assembled and clamped as soon as the adhesive has been applied. Even contact throughout suffices to ensure proper cure.

Standard Test Specimens
Unless otherwise stated, the figures given below were all 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 x 1 inch (12.5 mm x 2.5 cm) in each.

Tested at 25°C
