  Carbamates.

Does anyone know of the use of the term
"carbamates" as it relates to a BT epoxy resin system?

>From my understanding is that it has to do with a
moisture build-up at the molecular stage and when
exposed to a heat cycle the gases release?

Does normal baking release this bond on the layers
prior to lamination and/or after board has been
laminated?
