EPIBOND® 215 A/B

EPIBOND® 215 A/B Adhesive is an extrudable, two-component, room temperature-curing epoxy structural adhesive designed for service temperatures up to 300°F (149°C). This adhesive is suitable for bonding a wide variety of materials such as metals, composites, and many other dissimilar substrates. The combination of high peel strength and high shear makes this adhesive well suited for aerospace and other demanding applications. EPIBOND® 215 A/B structural adhesive can replace up to five competitive adhesives and is 75% lighter than mechanical fasteners.

Product Features
  • To maximize fuel efficiency, lighter is always better. And to improve productivity, using a single adhesive across multiple applications means assembly tasks are completed faster, and ongoing maintenance is kept to a minimum.
  • With up to 45% better peel, shear and compressive performance than many other structural adhesives, EPIBOND® 215 A/B adhesive can reduce Stock Keeping Units (SKUs) by 80% and help to lower fuel consumption by replacing metallic bolts and screws with a 75% lighter solution.
  • The superior performance of EPIBOND® 215 A/B adhesive helps to lengthen the lifetime of assembled parts by reducing maintenance requirements. It also provides a better, more reliable alternative to mechanical fasteners, which can reduce the base substrate tensile strength by up to 50%.
Features and Benefits
  • Room Temperature cure
  • Fast Handling Strength
  • Outstanding Peel and High Shear Strength
  • Service Temperature from -90°F (-68C) to 300°F (149C)

Application Information
  • 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.
  • This adhesive, however, has been designed to be effective in layers 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.

Technical Details & Test Data

Cured Properties

Unless otherwise stated, the data were determined with typical production batches using standard test methods. They are typical values only, and do not constitute a product specification.
Tests were done on prepared samples, such as phosphoric acid anodized and primed aluminum with appropriate surface treatment. Surfaces of steels and plastics were prepared by abrading with 210 grit sand paper / IPA wiping / Lint free towel drying / Nitrogen blowing. Unless otherwise noted, samples were cured 5 days at 77°F, and tested at 77°F (25°C).
