Abstract
A process is described for minimizing resin waste in the impregnation of a fibrous substrate with a thermosettable resin. The process involves the use of resin application means comprising a rotatable roller on which is deposited a liquid-form thermosettable resin; passing a fibrous substrate in countercurrent contact with the thermosettable resin on the rotating roller so as to transfer the thermosettable resin to the fibrous substrate; removing any untransferred resin from the rotating roller and depositing the removed resin onto the fibrous substrate prior to contact thereof with the rotating roller; and passing the resin-containing fibrous web to a heating zone to partially cure the resin. The process is particularly suited for application of a solventless resin formulation to a glass web in the preparation of a prepreg for an electrical laminate.
