Bonding Gar-Dur® UHMW PE

Criteria for Adhesive Selection

In selecting the best adhesive system for boarding Gar-Dur® polymer in a particular application, the following important criteria must be considered:

  • Type, severity and duration of stress and environment to which the bonded joint will be subjected.
  • Size and shape of the joint.
  • Substrate to which the Gar-Dur® polymer will be bonded.
  • Time, temperature and pressure conditions available for producing a satisfactory bond.
  • Availability of bonding equipment.
  • Cost.

Bonding

Use two part epoxy cement or neoprene based cement.

  1. Clean both surfaces well - such as with alcohol to eliminate even fingerprint oil.
  2. Roughen both surfaces - one side of the plastic and one side of whatever you are going to adhere to.
  3. Oxidize the surface of the plastic with an open flame; such as a hand held Benzomatic torch - just a couple of quick passes - do not blister the material.
  4. Apply adhesive to both surfaces - allow to dry until it becomes tacky.
  5. ress pieces together and clamp lightly - allow to sit overnight.
