Request Information
Epibond® 300 A/B Adhesive is an extrudable, two-component, room temperature curing epoxy adhesive designed for service temperatures up to 400 ºF (204 ºC). This product is suitable for bonding a wide variety of materials such as metals, composites and many other dissimilar substrates. The combination of high shear strength and compression makes this adhesive well suited for aerospace and composites such as liquid shim. Epibond® 300 A/B offers a fast cure, rapid build-up of lap shear strength with an easy to process mix ratio of 2:1 pbv.

Processing

Processing

 N/A Substrates to be bonded should be properly surface treated and be free from any contaminants. Mix both components thoroughly for several minutes until a homogeneous mixture is obtained or dispense from a 2:1 200 mL dual barrel cartridge through a suitable static mixer. For the 200 mL size, use TAH 9.375 mm dia. x 18-element spiral mixing nozzle or equivalent.

Note for Mix Ratio

 N/A The mixed adhesive should be spread with a spatula to the suitably pretreated dry joint surfaces. A layer of adhesive 0.004 to 0.012 inches (0.1 to 0.3 mm) thick will normally provide the maximum lap shear strength. However, this adhesive has been specifi
