Painting kevlar fabric impregnated with phenolic/PVB resin

Q. We are preparing to manufacture helmets molded from Kevlar fabric impregnated with phenolic/PVB resin. We will be using a water based polyurethane for the finish coats. What is the best method for ensuring that the paint adheres to this material? Are there primers that provide a surface for the finish to adhere to? Should we treat the surface by blasting or chemical etching?

Q. The PVB resin used can this also be recycled trim from windshield lamination production waste?
