9. A process for producing a thermal interface having protective coating sufficient to inhibit flaking of the particles of graphite, the process comprising (a) forming a sheet comprising compressed particles of exfoliated graphite, into the size and shape desired for a thermal interface, wherein the formed sheet has two major surfaces and at least one edge surface, and wherein the sheet has its directions of greater thermal conductivity parallel to the major surface;
- and (b) coating the major surfaces of the formed sheet with a material to form a protective coating, such that the material forms a protective boundary about the sheet wherein the material is coated on the formed sheet so as to flow completely about at least one of the edge surfaces of the sheet, and extend beyond at least one of the edge surfaces of the sheet.
