USE

 

  • If the epoxy glue is stored in a frozen environment, it must be taken out to room temperature before being thawed before use.During sizing, do not reduce the consistency of the glue by exposing it to high temperatures, unless prior tests have been done and shown to be feasible.
  • Apply the adhesive directly to the surface of the object to be bonded after oil removal, rust removal and coarsening treatment. Select appropriate tools to assist the adhesive coating and fix it with fixtures. It is then cured under the recommended heating conditions.
