ABSTRACT:
A process of applying catalyzed resin through a vacuum bag onto a dry hand lay-up uses at least one resin reservoir with a valve nozzle thereon. The valve nozzle is placed between the lay-up and the vacuum bag. By lifting the resin reservoir connected to the valve nozzle, the catalyzed resin placed in the reservoir will be sucked by vacuum onto the laminate. The lowering of the resin reservoir stops the flow. The vacuum bag between the valve nozzle and the reservoir connector must be broken first to allow an open channel to the valve nozzle outlet.
