Abstract
A mat material used in a sandwiched state between two members. The mat material includes a mat-like body portion having a first surface and a second surface, and an area containing an inorganic adhesive, with the area being formed on at least one of the first or second surface of the body portion, and the inorganic adhesive exhibits adhesiveness upon being heated.
Claims10
A mat material configured to be used in a sandwiched state between two members of a device that exhibits an operating temperature, where before the device reaches the operating temperature for the first time, the mat material comprises:
- a body portion;
- wherein the body portion is a single layered material, wherein the single layered material comprises inorganic fibers and has a first surface and a second surface;
- and
- wherein the inorganic fibers of the body portion do not extend beyond 1) the first surface and 2) the second surface;
- a layer of inorganic adhesive on the first surface or the second surface of the body portion, wherein the coated inorganic adhesive is substantially dry;
- wherein the inorganic adhesive in its substantially dry state exhibits adhesiveness upon being heated to the operating temperature, and
- wherein the inorganic adhesive comprises an alkali metal silicate.
