The coatings with controlled degree of hydrophobicity based on epoxy-polyester powder compositions on an aluminum surface were obtained. The study of changes in surface properties (contact angle and surface energy) and the physico-mechanical properties of the coatings, depending on the concentration of the fluorine additive, was carried out. Modification of the polymer powder composition with a fluorine additive leads to a sharp increase in the degree of hydrophobicity from hydrophobic to the formation of a superhydrophobic coating) and the saving of high mechanical properties of the coating obtained on them.
