Abstract
The paper provides the results of studies of lacquer coatings made on the basis of epoxy oligomers of different molecular mass hardened by the amine type hardeners. Thermal resistance, erosion resistance, strength and deformation characteristics of free lacquer films, as well as their physical and mechanical properties have been examined. It has been determined that the properties of epoxy lacquer coatings are significantly influenced by the molecular mass of the oligomer and hardener used to produce these coatings. It is shown that with the increase in the molecular mass used to obtain coatings epoxy oligomers improve their operational properties, such as heat resistance, erosion resistance, physical and mechanical properties.
