Highly Abrasion-Resistant Anti-Limescale Layers with High Chemical Resistance

摘要

The invention relates to the use of a coating of a layer including an inorganic, glass-like matrix of an alkali silicate and/or alkaline earth silicate or a layer including an inorganic-organic hybrid matrix or of a double layer of a base layer including an inorganic, glass-like matrix of an alkali silicate and/or alkaline earth silicate or a base layer including an inorganic-organic hybrid matrix and an alkali silicate-free and alkaline earth silicate-free top layer including a matrix of an oxidated silicon compound as the anti-limescale coating on at least one metal surface or inorganic surface of an object or material. The anti-limescale coating can be used for storage or transport devices for water or media containing water. The anti-limescale coating is suitable for pipelines, sand control systems or safety valves in the conveyance of oil or gas or the storage of oil or gas.
