Abstract: The present invention relates to a non-blocking roll of roofing membrane employing a combination of silicone rubber sealant, non-woven fiberglass scrim and pressure sensitive adhesive. The method utilizes a process by which silicone rubber sealant is applied to the top surface of the non-woven fiberglass scrim and made to penetrate {fraction (1/10)} to {fraction (9/10)} of the way into the thickness of the scrim, thus no silicone rubber sealant reaches the bottom or underside surface of the scrim. To the remaining {fraction (9/10)} to {fraction (1/10)} of the scrim's thickness and to the bottom surface of the scrim is applied pressure sensitive adhesive. This construction results into a self-adherent roofing membrane that can be packaged and transferred in roll form without the need to include an additional release liner sheet or non-blocking material such as talc, mica, or clay powder.

Abstract: Hygroscopic ceramic materials which are difficult to waterproof with a silane, substituted silane or silazane waterproofing agent, such as an alumina containing, fibrous, flexible and porous, fibrous ceramic insulation used on a reentry space vehicle, are rendered easy to waterproof if the interior, porous surface of the ceramic is first coated with a thin coating of silica. The silica coating is achieved by coating the interior surface of the ceramic with a silica precursor, converting the precursor to silica either in-situ or by oxidative pyrolysis and then applying the waterproofing agent to the silica coated ceramic. The silica precursor comprises almost any suitable silicon containing material such as a silane, silicone, siloxane, silazane and the like applied by solution, vapor deposition and the like. If the waterproofing is removed by, e.g., burning, the silica remains and the ceramic is easily rewaterproofed.
