Product Description
Araldite® EP 300 A/B Adhesive is an extrudable, two-component, room temperature curing epoxy
adhesive designed for service temperatures up to 400°F (204°C). 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. Araldite® EP 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
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.

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 specifically designed to be effective in layers of up to
0.12 in. (3 mm). The components to be bonded should be assembled and clamped as soon as the
adhesive has been applied. Even contact pressure throughout the joint area during cure will ensure
optimum performance.
