Summary The models for a description of main stages of formation and adhesion processes of polymer coating on the surface of the metal were proposed. The interactions with the surface of the primer layer and the steel sheet were taken into account. On the basis of the Langmuir's lattice model of adsorption, it was shown that there is an optimum temperature mode for drying oven. At this temperature, there is the greatest adhesion of monomers on a surface of a metal sheet. The modified model of “stick tape” was developed that describes the behavior of an adsorbed flexible macromolecule in an effective mean field created by intermolecular interactions with other polymer chains. It was shown that there exists a first order phase transition of the sufficiently large chains from the absorbed state to elongated one. This transition is accompanied by sharp jumps of degree of elongation, energy and heat‐capacity of the chains. It was found that there is an optimal temperature regime for the formation of the covering of metal sheet at which its production becomes the most quality.
