The following article deals with the results of series of tests for a range of modified epoxy composites, which are intended to be used as protective coatings in corrosive environments. Corrosion of different nature presents itself as a cause of concern in numerous branches of industry. This fact calls for research to implement new types of protective construction materials. Epoxy resins have proven their resistance to chemically aggressive environments. To improve their technological properties further, numerous additives and plasticizers are being used. In this case, we use industrial waste to try and improve the properties of modified epoxy composite. Construction materials based upon epoxy binders are often being subjected to mechanical load cycles of dynamic nature. As such, impact strength of said materials needs to be brought into question. Technological properties of epoxy waste-filler based composites with high degree of filling have been researched. Among those properties the impact strength of composites is considered one of the most important ones. The samples have been exposed to different types of environment to determine the dynamics of change of key properties’ values. Regularities concerning the changes in impact strength values, depending upon environmental exposition and type of compositions, have been pointed out. Features of structural formation of impact-resistant material types have been evaluated.
