I've been vacuum laminating veneers of .3 and .6mm for purflings (multiple line marquetry) on my guitars, using polyurethane glue. For the most part this has worked well. When the glue manufacturers switched to a less viscous formulation, I found I got a lot more bleed through which led to occasional whisper thin white glue lines when different layups were combined.
So the question I have is what kind of veneer glue would you recommend for laying up multiple laminations, say as many as 3-4 veneers, that will eventually get bent on a hot pipe, or in the case of bindings (the decorative edging set into the sides of guitars), bent and kept at 310F for 30 minutes in order to have the wood (in my case ebony) set the bend. The glue needs to be heat resistant, so as the veneer lines particularly on bindings do not release and ripple as they're bent. If there's a solution that's water free, I'd be interested in that as it won't have the propensity to cause the veneers to curl when I'm trying to get them into the bag.
Thanks in advance,
David
