| abstract |
The invention relates to the use of a coating of a layer comprising an inorganic vitreous matrix of an alkali metal and/or alkaline earth metal silicate, or a layer comprising an inorganic-organic hybrid matrix, or of a double layer composed of a base layer comprising an inorganic vitreous matrix of an alkali metal and/or alkaline earth metal silicate or a base layer comprising an inorganic-organic hybrid matrix and an alkali metal and alkaline earth metal silicate-free outer layer comprising a matrix of an oxidic silicon compound as anti-lime coating on at least one metal surface or inorganic surface of an article or material. The anti-lime coating may be used preferably for storage or transport facilities for water or water-containing media, such as water-containing oil or gas. The anti-lime coating is particularly suitable for pipelines, sand control systems or safety valves in oil or gas conveying or oil or gas storage. |
