    Abstract: Method for forming and adhering an entrained polymer structure to a substrate (114), applying the polymer in molten form to form a solidified polymer structure on the substrate. The polymer includes a monolithic material formed of a base polymer (25) and a mineral active agent (30). The surface of the substrate is compatible with the molten entrained polymer so as to thermally bond with it. Used is a hot melt dispensing apparatus comprising: an extruder (102) for providing a flow of the polymer in molten form; one or more hoses (104), each of which having an internal lumen (108) in fluid communication with an exit (106) of the extruder to receive the flow of the polymer in molten form, the lumen terminating at an applicator (110) to which the polymer in molten form is conveyed; the applicator comprising a dispenser (112) for repeatedly applying the polymer to the substrate.
