COMPOSITION FOR PREPARING SUPER-HYDROPHOBIC COATING Russian patent published in 2010 - IPC C09D183/08 C08J7/04 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention discloses a composition containing the following (wt %): a surface hydrophobisation component - fluoro-hydrocarbon silane containing hydrolysable functional groups of general formula YCF₂ (CF₂)_n CH₂-O-(CH₂)_m- SiX₃, where Y denotes F or H; n is an integer from 3 to 11, m = 2 or 3; X is a functional substitute selected from: CI, OCH₃, OC₂H₅, OC₃H₇, OC(O)CH₃, NH₂, N(H)CH₃, N(CH₃)₂, N(C₂H₅)₂ (1-1.5); texturing filler - aerosol (1-1.5); siloxane binder - polyamino-functional siloxane oligomer of formula [CH₃(H)N]₃Si[OSi(CH₃)C₆H₅]₃O-Si[N(H)CH₃]₃ (0.1-0.2) and organic solvent selected from aliphatic ethers and aliphatic ketones (the rest). The disclosed coating composition is suitable for high-voltage lines.

EFFECT: composition enables to obtain a coating which is characterised not only by high wetting angle values, but by prolonged water resistance, the method of depositing said composition does not require preparation of surfaces to create a super-hydrophobic effect.
