Epoxy bonds to Diolen very well.

I'm a bit confused about what you are actually doing, can you post some photos? Video probably  not necessary, but some photos would help.

What are you gluing if the Diolen is already bonded to the wood? Why does the wood have a peel ply texture? Are you first laminating the Diolen with peel ply, letting that cure, then removing the peel ply and bonding to the wood? If so, how are you bonding it to the wood, just the same laminating epoxy? If that is the case, what are the glues for? Why not just laminate the Diolen to the wood directly?

My initial suspicion is the epoxy, can you tell us what it is or post a TDS for it? A 72 hour epoxy does not sound like a room temperature cure epoxy, it sounds like it would need some sort of elevated temperature cure to achieve it's full properties. If this is the case, then it will be extremely brittle after curing at room temperature, and extremely easy to peel apart as a result.

Hi,

I've laminate a sheet of the Diolen 200g black with 72h epoxy (1h work, bought from a local dealer)
the surface was a peel ply surface (the red line one you offer)


I have a specific project with a hard requirement that i need to glue the Diolen to birch baltic plywood.
I've created a test with multiple glues to try and set them up 
But never actually got to test the glues themselves because the surface of the laminated Diolen was the first one to fail, detaching from the wood leaving the peel ply surface on the wood and came out bare bone.

Now one reason can be the epoxy itself, which i think is less likely
The lamination process itself could be the problem? just a fabric on the table with some weight on it (flat object)

Can it be that Diolen does not bond to the epoxy very well?

* I've done a video of the process, posting it is a lot of work for me but if its crucial to figuring it out i will post it per request.

Will appreciate your help, i'm working on it for a long time and its currently a bust, i'm discouraged
