Adhesive Films

Adhesive films for a variety of bonding applications. We developed the EF range specifically for bonding honeycomb core to aluminum or fiber-reinforced skins. These films provide excellent adhesive properties over a wide range of core to skin requirements. Curing temperatures from 50°C (122°F) and service temperatures as high as 126°C (259°F).
