The use of styrene-acrylic paints is an affordable and reliable way to protect buildings and premises from external factors, including electromagnetic radiation. It is known that shungite is used as a filler in radioprotective polymer compositions (polyurethane, polyethylene, rubbers). However, there are few data to determine its effect on the durability and resistance of acrylic-based protective coatings. It was found that the application of a protective filler allows maintaining an increased level of adhesive strength of coatings to concrete (over 3.0 MPa) and steel (over 1.5 MPa) substrates. It is shown that the exposure of styrene-acrylic free films in aggressive media for 7 days causes a decrease in their elasticity, a change in color characteristics, assessed by the CIE Lab method, which is accompanied by the formation of a white bloom on the coating surface, detected by the microphotographic method. The obtained result can be explained by the chemical interaction of aggressive media on the components of the polymer composition (film). The absence of the formation of defects and the uniformity of free films after their exposure in aggressive media was also noted.
