Epoxy system SR7100 / SD7106 (Fast)

 

Epoxy structural adhesive SR7100 / SD7106 for thin bonding with fast hardener

 

Each kilo includes 0.69 kg resin + 0.31 kg hardener

 

ISOBOND SR7100 / SD7106 epoxy system has been specially formulated for thin bonding from 0.1 mm to a few mm. It exhibits high fatigue strength and excellent resistance against microcracks propagation. Application on nonporous surface material is possible. The hand mixing for quantities greater than 200 or 300 grams can be complicated and induce significant risks of inhomogeneous mixture in production. A machine of dosing and mixing may then be considered and become essential in order to avoid any difference in quality.

 

- High performance adhesive
- Adheres to most materials
- Specifically designed for composite structural bonding
- Excellent resistance against microcracks propagation (high GIc)
- Gel texture easy to apply and mix
- Outstanding wettability of surfaces
