<p>Improvements in adhering polyvinyl fluoride sheets to other materials by making a novel sheet composed of polyvinyl fluoride in sheet form and a layer of adhesive, preferably a polyurethane adhesive, on an appropriate surface, or portion of a surface of the polyvinyl fluoride sheet. This composite adhesive sheet must be made in a special way by coating a solution or dispersion of the polyvinyl fluoride onto a suitable surface, removing the solvent or dispersing medium to a residual content of about 0.4 to 0.8 weight percent, applying the adhesive, preferably as a solution or dispersion, in the area required, and then removing the remainder of the solvent or dispersant from both the polyvinyl fluoride sheet and the adhesive layer.</p> |
