Influence of nanodispersed powder of silicon dioxideof tarkosil T-20 brand on strength characteristics of paint and varnish coating from enamel XB-16

The influence of nanodispersed silicon dioxide on the mechanical characteristics of the paint coating of enamel XB-16 was studied, the optimal content of nanopowder was revealed, at which the coating has a maximum microhardness. It was revealed that nanopowder additives increase the microhardness of the coating almost one and a half times in comparison with the microhardness of the original coating. Intermolecular bonds in the polymer coating and their changes during modification of enamel by nanodisperse powder were determined by IR spectroscopy.
