Coatings based on the developed mixture are evaluated for anti-icing capabilities. It was demonstrated that after 72 hours of wetting, the coatings based on the suggested composition preserved their superhydrophobic properties. On the mortar substrate, the wetting angle was greater than 150 degrees. Coating adhesion to the substrate after wetting was rated as 1 point. The findings of an evaluation of ice adhesion to a superhydrophobic metal surface are presented. The force of detachment of a drop of water on a superhydrophobic metal surface is proven to be three times less. Its anti-icing characteristics allow a drop of water to glide off the surface more easily. It has been demonstrated that ice adheres to a superhydrophobic surface less than a hydrophilic one. On a hydrophilic and superhydrophobic surface, there is no difference in the rate of ice evaporation. According to the research, the proposed composition generates a covering with anti-icing qualities that lasts in service.
