Operation process
If the epoxy adhesive is stored in a frozen environment, it should be removed and defrosted at room temperature before use. During use, the glue should be avoided in a high temperature environment to reduce the consistency of the glue, unless it has been tested in this area and confirmed 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. Then solidify according to the recommended heating conditions.
