Adhesive bonding to electroless nickel

2006

Our company recently experienced an adhesive bond failure to electroless nickel. The adhesive separated cleanly to the electroless nickel surface, which was previously abraded with 400 grit sandpaper.

Is electroless nickel inherently difficult to adhesively bond? What parameters affect bond strength?

It can be tough to glue to EN as it is very smooth. A slightly used sandpaper, even a good one, will not abrade as well as a new one. A long time ago, we had a problem trying to mask a SS part. When it was baked at 400F for a half hour, the tape stuck very well. You might try it. You might try 320 and 280 wet and dry sandpaper to see if it might work better and eStablish a "QC" check for how well it is roughed up vs failures.

Locktite makes an adhesive that bonds well to EN. UnfortunAtely I don't know the specific product.
