Preliminary treatment of surfaces to be glued 

Careful preparation of the surfaces to be glued is required to ensure proper connection between the glue and the surface of the parts to be connected.

After removing old glue, dirt, rust, paint or oxidation layers from bonding surfaces grind gluing flange down to bare metal

On aluminum surfaces use Cr-Ni wire brush.

Then treat flange with Saco-Roc abrasive paper (both included in Al package).

Apply mixed primer only on bare flange areas, if they were cleaned previously with a brush or lint-free cloth

Do not touch cleaned areas without gloves (transfer of sweat from hands).

Then apply mixed primer to the prepared gluing surfaces with a flat brush.

The result is positive when a uniform coat of primer is visible. If this is not the case, repeat treatment.

Start bonding work after primer has been wiped off with lint-free cloth after positive result has been achieved.
