Abstract
Abstract An article suitable for use in bonding to metal, glass, or ceramic substrates at high temperatures, e.g., above about 400° C, comprises (a) a thermally stable backing material, such as a metal foil or an inorganic fabric; and (b) a coating on at least a portion of at least one major surface of the backing material, the coating consisting essentially of fused or fusible particles selected from glass particles, ceramic particles, and mixtures thereof. Preferably, the coating further contains a non-pressure sensitive adhesive vehicle such as pine oil, to aid in application and retention of the particles.
