Abstract: In order to provide a method by means of which the surface of substrates can be protected from corrosive attack and which, in particular, avoids the necessity for oxidative treatment to form oxide layers on surfaces or for phosphatizing or chromatizing treatment steps and is, in addition, simple to apply, it is proposed that the substrate be brought into contact with a solution of a polymer which exhibits UCST properties and which is caused to be deposited onto the surface of the substrate as a layer by decreasing the temperature of the polymer solution.

Abstract: In order to make it possible to treat particles in such a manner that they are stabilized as disperse particles in liquid media, such as varnishes, a method of coating particles with LCST polymers is proposed which is characterized by the following steps: a) dissolution of an LCST polymers in a solvent at a temperature below the LCST; b) mixing the solution obtained in step a) with the particles to be coated; and c) increasing the temperature of the mixture obtained in step b) to or beyond the point at which the LCST polymer deposits onto the particle surfaces.
