ABSTRACT:
The method of constructing multi-layered hoses of plastic materials in which a coating comprising resorcinol, urethane adhesive and a solvent is applied to the outer surface of an inner tubular member or layer of either polyamide or polyester with the solvent acting as a carrier for the resorcinol and adhesive, removing a major portion of the solvent from the coating, and applying an outer tubular layer of a plastic material such as polyamide, polyester, polyurethane or polyvinyl chloride, but of a different material than the inner layer, over the inner layer in contact with the coating. The resorcinol plastisizes and wets the outer surface of the inner layer and the remaining solvent wets the inner surface of the outer layer whereby molecules of the adhesive interact with molecules of the two layers to share electrons therewith for establishing a strong bond therebetween, the amount of the remaining solvent being sufficient for wetting the outer layer but insufficient for creating gas bubbles between the inner and outer layers.
