PERMABOND® ET505 is a two-part, 1:1 mixable epoxy adhesive. ET505 is a semi-flexible toughened epoxy adhesive with good adhesion to a variety of substrates such as wood, metal, ceramics and some plastics and composites. Permabond ET505 forms tough bonds providing high peel resistance and high shear strength. The extended work life of this product allows for adjustment and makes it more suitable for larger applications.
FEATURES AND BENEFITS
- Adhesion to a wide variety of substrates
- Full cure at room temperature
- Easy to apply
- High shear and peel strength
