Purpose: The paper presents the problems of forecasting of durability of waterborne acrylic coatings and epoxy coatings designed to protect devices and machine elements. Design/methodology/approach: The durability forecast has been performed on the basis of analyses of time series with the use of trend function extrapolation. Mechanical properties such as: scratch resistance, impact strength, grindability and luster have also been evaluated. Moreover, besides standardized methods, some complementary methods have been applied in the form of analyses of microscopic images of damage caused by the exposition of coatings to corrosion. Findings: Assuming five-year durability for coatings on devices and machine elements (time between overhauls), one can find that investigated waterborne coatings can be a successful protection of devices and machine elements in the established range and in the dependence on the applied system. Research limitations/implications: The research has shown some substantial influence of coating system width changes on obtained results of scratch resistance and impact strength. It should be beneficial to extend further research with the description of the mechanism that enables to obtain some strict correlation between the investigated properties of coatings and the allowance of their width. Practical implications: The research makes possible to determine the areas of application for coatings obtained from waterborne materials to anticorrosion protection of devices and machine elements. This enables to eliminate gradually traditional solvent coatings (of high VOC content), which are disadvantageous to the environment. Originality/value: The applied sequence of research can form a proposal of the method to evaluate coatings made of some other than investigated waterborne materials predestinated for machine industry.
