Abstract
A process of coating an open-cell foam substrate includes the steps of arranging two rollers separated by a gap; positioning the substrate above the gap; providing a coating material onto the substrate, feeding the substrate through the gap so as to achieve a layer of the coating material on the substrate, wherein the coating material is selected from the group consisting of a polysiloxane derivative, acrylic polymer, butyl rubber, natural rubber, nitriles, styrene block copolymers with ethylene, styrene block copolymers with propylene, styrene block copolymers with isoprene and polyvinyl ether and modifying the coating with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers; hexamethyldisilazane; and silica.
