Nora: I would highly recommend consulting with your adhesive vendor. They should be able to identify a time which would assure optimum results of the adhesive after sitting idle. I am sure it depends on the environmental conditions of your facility (temperature and humidity) with some adhesives. If the vendor throws the ball back into your lap then a DOE would be warranted.
