Abstract

A structure comprising at least one inorganic layer comprising inorganic materials suitable for use 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 structure. 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 pollution control device is assembled.
