Highly hydrophobic anti-icing coatings

Abstract

Abstract The anti-icing coatings with increased hydrophobicity based on epoxy-polyester powder compositions on an aluminum surface were obtained. Modification of the polymer powder composition with a organofluorine additive leads to a sharp increase in the degree of hydrophobicity (up to the formation of a superhydrophobic coating) and the saving of high mechanical properties of the coating obtained on them. The adhesion of a superhydrophobic coating to ice and the resistance of a superhydrophobic coating layer to icing/deicing cycles were studied. The developed super-hydrophobic coating has a low ice adhesion value and long-term resistance to icing/deicing cycles.
