Abstract

The possibility of improving the technological and operational properties of coatings based on single-component water-dispersion primers and enamel by introducing nanodiamond particles is investigated. The paint and varnish materials were modified with nanoscale additives in the amount of 0.005–0.100 wt. %. The drying time and physical and mechanical properties of single-layer coatings made of modified paint and varnish materials (hardness, impact strength, adhesion) on metal substrates were studied, and the protective properties (resistance to static effects of water, 3% NaCl solution, industrial oil, diesel fuel) of coatings based on modified primer and enamel compositions with the best mechanical properties were evaluated. The coatings were obtained in accordance with the technologies used by the private unitary enterprise “MAV” (Republic of Belarus).
