IN LINE WEB TREATING AND SUBSTRATE FORMING METHOD FOR OVERLAID PRODUCTS

摘要

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 a gent; placing the treated web directly adjacent an unconsolidated substrate wherein the unconsolidated substrate comprises an uncured first resin; and c oncurrently consolidating the unconsolidated substrate and curing the bindin g agent and first resin thereby bonding the web to the substrate without add ition of a separate adhesive. An overlaid composite product produced by this method is described. An overlaid composite product can be, e.g., a paper la minated oriented strand board.
