When you want to assemble two metal parts with our structural adhesives (TECHNO BOND 3054, 3056, 8003, 8050, 8011, 8104, 8105 and 8106, among others), it is vital to undertake surface preparation on the metal, through either sandblasting, or manually with grade #80 sandpaper, followed by acetone cleaning, to remove oxidation from the metal surface and to create a surface profile.
Afterwards, it is essential to apply the adhesive quickly since oxidation starts as soon as your surface pre-treatment is completed, leading to a new layer of oxidation within 24 hours (a greasy coating that creates a barrier between metal and adhesive).
Thus, we suggest that you apply our adhesives as soon as you finish the pre-treatment of the metal surface in order to get optimal results.
