Abstract

The work focused on determining the dependence of the anti-icing properties of coatings on hydrophobic properties. The coatings were applied by pneumatic spraying and did not have a clearly structured roughness structure. For the study, polymer coatings of various chemical natures were selected based on: organosilicon copolymer, copolymer of vinylidene fluoride and chlorotrifluoroethylene, fluoropolyurethane, epoxy varnish, acrylic copolymer, poly-dieneurethane with epoxy end groups and fluorosiloxane rubber. The dependences of ice adhesion on the contact angle of wetting, roughness and freezing time of water were determined.
