Study of the effect of modifying alkyd enamel paint on its heat resistance, UV resistance, and chemical resistance properties

Although the use of nano-additives can improve the corrosion resistance of some organic coatings, it can lead to deterioration of other coating properties, such as resistance to thermal changes, ultraviolet radiation and chemicals. In this paper, the effect of carbon nanotubes coated with silicon oxide nanoparticles on the resistance to thermal changes, ultraviolet radiation and chemicals of alkyd enamel coating is investigated. To study these properties, a heat resistance test according to ASTM D573, a UV resistance test according to ASTM G155 and a chemical resistance test according to ASTM D5402-93 (1999) were conducted. The experimental results showed that the addition of nano-fillers led to an increase in resistance to chemicals with an increase in the mass concentration of nano-fillers to 0.349%, however, after this limit, the effect of chemicals on the paint increased, and the additive did not lead to a deterioration in resistance to thermal changes and ultraviolet radiation.
