Heat resistant veneer glue

      There are glues that will withstand the high temperatures in heat-assisted finishing operations. 1998.

Q.
I'm looking for some glue to apply a veneer face to a curved plywood panel on a reception station. This glue will need to withstand temperatures of 150 degrees three times at 20 minutes when this unit goes through my finishing process.

We use a finish material that needs to be heat cured in sealer and topcoat. We've had trouble with glues pulling loose at this temperature.

A.
You have discovered the weak point of the common white glues and similar products. The best glue for this purpose would be a film adhesive that needs heat to cure but then once cooled will not soften with additional heat.

If this is not possible in your operation, then let's look at a cross-linking adhesive--melamine would be a good choice, urea a second choice. Contact an adhesive salesperson rather than just a store that sells glue for the best formulation.
