| Abstract: | The corrosive effect of simulated acid dew on the properties of coatings and paints using intensive contact tests has been conducted. The results showed that repeated formation and prolonged adsorption of acid dew on the surface of construction materials could accelerate deterioration and aging of the materials. Deterioration and aging of paint coatings were increased with the increase in acidity of the simulated acid dew as shown in the following sequence: pH3.0>pH4.5>pH5.6. |
