Abstract (en)
[origin: WO2005066285A2] The invention relates to hydrophilic coating for surfaces, containing one or several polysilazanes and an ionic reagent or mixtures of ionic reagents. The polysilazane is, in particular, a polysilazane of formula 1, (SiR'R"-NR" )n- (1), wherein R', R", R" can be identical or different and are either hydrogen or organic or metalorganic radicals. n is measured in such a manner that the polysilazane has a numerical average molecular weight ranging from 150 - 150.000 g/mol. In a preferred embodiment, the polysilazane is a perhydropolysilazane (R'=R"=R" = H). The ionic reagent is, preferably, a salt of a carboxylic acid, in particular a hydroxycarboxylic acid, or a cationic or anionic silane, or an oligomer or polymer. The invention also relates to a method for the production of the above-mentioned hydrophilic coatings.
