This paper presents the results of an investigation into the adhesion properties of release coatings based on polyisobutylene applied to metallic substrates. A software tool was developed in Microsoft Visual Studio using the C++ programming language to compute the composition and effective technological parameters for forming coatings that ensure optimal adhesion to protected surfaces. As a case study, the method of calculating the relationships between composition, temperature, and formation time is demonstrated for coatings achieving the highest adhesion, corresponding to a score of “zero” on the standardized six-point cross-cut adhesion test. It is shown that the application of the developed software enables parameter evaluation within 1–2 seconds. The computational results are experimentally validated. The morphology of the coatings was examined using optical microscopy. It was observed that no delamination occurs at the intersection points of cuts or within the grid pattern.
