ABSTRACT:
An improved method for producing a reinforced hose. A tubular core is extruded and then heated in a microwave oven to at least partially cure the core. While the core is still hot, a powdered hot-melt adhesive is electrostatically coated onto the core and forms a fusion bond with the core. The coated core is cooled, a reinforcement is applied to the core, an optional outer coating is applied and then the composite is heated to finish curing of the hose and to melt the adhesive to bond the reinforcement to the core.
