FIELD: chemistry.
SUBSTANCE: composition represents "ripe" solution of film-generator in solvent of general formula CnF2n-1H3O or CnF2nH2O, n=2-5, wherein as film-generator applied is mixture of polyogranosiloxanes with molecular-weight characteristics Mw=1000-160000, Mn=900-70000, which is result of polycondensation of products of reaction of hexafluoracetone and 3-aminopropyltriethoxysilane.
EFFECT: invention makes it possible to form from composition coverings, which have hardness 5H, transparency in the range 350-2700 nm, reflection index 1,30-1,35, temperate hydrophoby and very smooth.
