Abstract
A method for preparing an overlaid composite product comprises treating a web comprising a functional barrier on one face of the web with a binding agent; placing the treated web directly adjacent an unconsolidated substrate wherein the unconsolidated substrate comprises an uncured first resin; and concurrently consolidating the unconsolidated substrate and curing the binding agent and first resin thereby bonding the web to the substrate without addition of a separate adhesive. An overlaid composite product produced by this method is described. An overlaid composite product can be, e.g., a paper laminated oriented strand board.
