Abstract

A mounting mat () comprising at least one inorganic layer () comprising inorganic materials suitable for mounting a pollution control element in a pollution control device. A friction-inducing material () is disposed on at least one side of the inorganic layer (). The deposited friction-inducing material () defines a higher friction area exhibiting a static coefficient of friction higher than that of the inorganic materials. A lower friction layer () is disposed so as to cover at least a portion of the higher friction area and define an exposed surface area of the mounting mat (). The exposed surface area exhibits a lower static coefficient of friction than that of the higher friction area. The lower friction layer () no longer covers a substantial portion of the higher friction area, after the mounting mat () mounts a pollution control element () in a pollution control device ().
