Glueing
Glueing
(OP)
I'm glueing a Pebax 72D tube to a PC touhy borst with UV light and I'm getting poor results. I'm getting lots of voids and bubbles after curing. It looks like the glue is delaminating from the Pebax. It's a Dymax glue and the glue gap is 0.5mm. I've tried adjusting light intensity, distance from light guides, curing time. My next step is to reduce the glue gap to reduce shrinkage/delamination.
Have anyone come across this problem before?
Thanks & Regards

RE: Glueing
3M make a range of glues and adhesive tapes that might work, but assembly methods will be a problem.

RE: Glueing
Do you think you might be using to much?
Did you prepare the surface?
How are you applying the glue? Syringe, 10cc or 30cc?
Sorry for all the questions? I am not an expert, just trying to help.
Thank You

RE: Glueing
If you can provide information on the specific Dymax adhesive used, we can help identify if you are using the best one for the application.
Reducing the gap will not help if the adhesive does not bond to Pebax.
