Abstract

A method of making a flat gasket comprising a non-woven mat having opposite faces, including the steps of impregnating the mat with a polymerizable liquid impregnating agent and applying to at least one part of at least one mat face a coating containing a polymerizable polymer material. The coating is applied to the impregnated mat prior to polymerization of the impregnating agent. The impregnating agent and the coating are simultaneously polymerized in one operation.
