Abstract: This composite uses the bonding of PVC to a variety of materials, from cloth to concrete, by the simple laying of the PVC surface to the other surface without the use of conventional wet, tacky, intermediate layer or layers of conventional adhesives. A simple preapplication of a chemical intermediate to the second surface in latex form and dried to a nontacky state is done. This is followed in any length of time thereafter with the simple contact of both surfaces, one to the other. A mild to aggressive tack bond, or a hard permanent joining of both surfaces is achieved. This bond is formed by the polar attraction of certain acrylics to the plasticizers in the PVC.
