Since there is no air movement inside the vacuum bag, does the Better Bond cold press glue actually cure?
With a cold press glue, the bond is set inside the vacuum bag when the air inside the pores of the veneer and the substrate is displaced by the adhesive. This typically takes 45 to 60 minutes to occur. The curing process takes place outside of the bag after the glue has set. At this point, the panel is removed and allowed to cure outside of the bag. This concept applies to all standard non-catalized cold press veneer adhesives. There are some veneer glues that have a chemical or reactive curing process. Ultra-Cat veneer glue is urea resin glue which has a reactive affect when mixed with water. The water does not need to evaporate to cure the adhesive. With this adhesive, the set and the curing takes place inside the vacuum bag over the course of 2 to 6 hours (depending on temperature).
