- Application Information
- EPIBOND® 315 A/B structural adhesive is not only versatile, it can improve production throughput by up to 80%.
- Parts exposed to demanding conditions may require heat resistance and high compressive strength. And on the manufacturing floor, avoiding bottlenecks is key to maximizing productivity.
- With a superior service temperature of 400°F/200°C, EPIBOND® 315 A/B adhesive provides reduced maintenance and increased part lifetime across a wide range of applications. Its high heat resistance and compressive strength enables its use as a liquid shim in areas where metal shims are currently used.
- Curing EPIBOND® 315 A/B adhesive at room temperature is up to 88% quicker than competitive adhesives, with a 75% faster time to handling strength. Easy to use and fast to cure, parts can be made in one working shift.
What makes EPIBOND® 315 A/B structural adhesive different?
EPIBOND® 315 A/B adhesive is a two-component, room-temperature curing epoxy structural adhesive specifically designed for demanding applications requiring high heat resistance and compressive strength.

- Processing Guidelines
- Substrates should be properly surface treated and be free from any contaminants.
- Mix both components thoroughly for several minutes until a homogeneous mixture is obtained.
- Mixing with a centrifugal mixer such as a FlackTek, Hauschild, or Thinky mixer can improve results. Total mixing time at 2000 rpm should be kept below 1 minute to avoid excessive heating.
- Dispensing from a 2:1 dual barrel cartridge through a static mixer is the preferred method.
- The mixed adhesive should be applied to both dry joint surfaces with a spatula.
- 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.
