Directions for use

  1. Before applying Born2Bond Flex, make sure the surface is clean, dry and grease-free.
  2. To use, Part A and Part B must be blended.
    • The product can be applied directly from the syringe using the plunger supplied and dispensed through the recommended mixing nozzle.
  3. Hold the syringe upright and insert the plunger.
    • While keeping the syringe in an upright position, remove the cap, attach the mixing nozzle, and begin dispensing the adhesive upward until any bubbles present in the smaller component have been removed.
  4. Dispense and discard a bead as long as the mixing nozzle, to ensure sufficient mixing.
  5. Apply the mixed adhesive to one of the bond surfaces to be joined.
    • Parts should be assembled immediately after the mixed adhesive has been applied.
    • Bonds should be held by fixing or clamping until the adhesive has cured. Prevent assembled parts from moving during cure.
    • The bond should be allowed to develop to full strength before being subjected to any service load (typically 24 hours).


The common applications of this product are bonding leather, making elastic and waterproof joints, flexible bonding, bonding floor coverings and particle boards, damping vibrations, reinforcing parts, bonding glass and rubber.
