PERMABOND® ET515 is a 1:1 mixable epoxy adhesive. ET515 is a semi-flexible toughened adhesive with good adhesion to a variety of substrates such as wood, metal, ceramics and some plastics and composites. It’s a relatively fast curing epoxy; reaching handling strength in 20-30 minutes. It is ideal for bonding different materials where differential thermal expansion is anticipated.
FEATURES AND BENEFITS
- Adhesion to a wide variety of substrates
- Full cure at room temperature
- Easy to apply
- Semi-flexible
- Good impact strength
