A program has been developed that allows to evaluate the adhesion of paint coatings by means of analyzing images of the surface of coatings with delamination’s from the substrate to be protected. The program is written in Kotlin using JavaFX platform and is focused on tests carried out by the method of lattice cuts within the conditions of paint and varnish production. Through the work the evaluation of the area of the coating detachment from the surface to be protected is being held and the obtained result is scored by points according to the method of lattice cuts. The use of the program does not require a large computing power of the computer and reduces the time for obtaining the calculating results for one sample from 20 minutes to 3 seconds.

Investigated the influence of contents of sodium - carboxymethylcellulose, glycerin and powder Fe on electrical properties of composite coatings. Proposed regression model describing the relationship of the values of the electrical resistivity of the coating and dielectric strength to their composition used to predict the electrical properties of the formed coatings. Showed the correlation between the microstructure of coatings with Fe powder and electrical properties.
