ABSTRACT:
A ceramic fiber insulation material is disclosed. It is prepared from a precursor blend generally comprising a gelled colloid and a ceramic fiber filler. Other filler, e.g., other fiber of refractory material, is contemplated, particularly when mixed with ceramic fiber. The gelled colloid ban be formed such as by mixing a gelling agent with a colloid of inorganic oxide or by blending anionic colloid with cationic colloid. The gelling agent is typically nonionic and water-soluble. The blend is trowelable, pumpable and possesses excellent adhesive characteristics including the ability to stick to most surfaces, including metal surfaces. The blend is also virtually shrink-free during drying and, after drying, can provide the insulation material.
