Request Quote Request Sample

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
