Hello all, we are currently using J-B Weld # 8280 (aka 8281) two component epoxy to bond small pieces of urethane to zinc plated mild steel. These urethane pieces are not critical in any way to the function of the assembly, more of just a minor convenience so if they fall out off in the field, obviously we don’t want that but it’s not the end of the world. Issue is, we are getting complaints that the urethane pieces are falling off on the way to the customer, not even getting out to the field before having issues.
We have a reference model on hand from 2017 and when I compare it to current production models I can see a substantial difference in quality over how the epoxy was applied. In this particular case there was much more epoxy than what was needed, but with the labor situation we all deal with today, the next batch could just as easily not have enough epoxy.
All that to say, this is likely operator error, however I still want to cover all my bases. After doing a quick look on the J-B Weld website, it looks like their 8265S may be better for our needs. Looking for thoughts on if you all would agree with that, as well as any products from other companies that may be better than that. I’m sure the purchasing dept would like it if we stayed with a J-B W product but they will change if we need them to.
Completed assemblies will likely be outside 24/7 in assorted weather, but no unnatural hot/cold situations. Will be subject to repeated light impacts but for relatively short periods of time.
