In recent years, materials of nanometric size have become the object of interest of scientists, due to the possibilities of using them in various industries, including the paint and varnish industry. Companies are looking for new solutions and patents to make coatings mainly environmentally friendly as well as harmless to people. Very often, scientists use nano-metals or their oxides, because they are characterized by different properties at the nano-scale. The aim of the study was to obtain silver nanoparticles by reducing silver nitrate and their addition to the paint composition. The stability and size of particles of dispersion systems containing nano-silver have been examined. It was found that the nano-silver content in the amount of 2% (w/w) exerts a positive influence on the stability. More detailed analysis has shown that the dispersion system under consideration undergoes the normal distribution. More amount of nano-silver makes the particles smaller. The studies of the thermal properties of the layers obtained from the paint composition showed that the increase in the nano-silver content in the system shifts the range of the film temperature towards higher values. Consequently, the layer becomes harder and less flexible. Derywatography analysis has indicated that the maximal temperatures of the exothermic effect−after addition of nano-silver particles−lead to higher temperature values in the systems. It was shown that the addition of nano-silver into the varnish composition has a beneficial effect both on its stability (backscattering, turbiscan stability index) and the properties of the layers formed.
