That's the point.

There is not much needed for what you want to glue.

I know that regular (for "them") or normal (for "us") ;-) epoxy is much 
stronger
than 5 min epoxy but look at your application.

You have a GIANT surface, and only very little separation forces.

I think roughing the copper is just overkill.
But if you peel off the copper of a precoated board you can see it is 
roughened at the adhesive side.
So there seems to be some point in that.
