Pretreatment of bonding surfaces 

Careful preparation of the bonding surfaces is required to ensure proper connection between the adhesive and the surfaces of the parts to be joined. After removing old adhesive, dirt, rust, paint or oxide layers from bonding surfaces, the adhesive flanges can be ground down to bare metal.

On aluminum surfaces, use CrNi wire brush. Then treat flanges with Saco-Roc sand paper (both contained in Al scope of equipment). The mixed primer can only be applied to the bare flange areas if they have been cleaned beforehand with a brush or lint-free cloth.

Do not touch cleaned areas without gloves (transfer of sweat from hands). After this, the mixed primer can be applied to the prepared bonding surfaces with a flat brush.

The result is positive when a uniform film of primer is present. If this is not the case, repeat pretreatment. Start bonding work after primer has been wiped off with lint-free cloth after positive result has been achieved.
