The degradation of silicone coatings in high temperature atmospheres
Abstract
To evaluate the degradation of silicone based coatings that protect the mild steel surfaces from corrosion in high temperature atmospheres, the coatings were exposed to muffle furnace for heating ‐ cooling cycle (as per ASTM specification D 2485) up to 700°C. The ability of the paint film to withstand the temperature is related to its resistance as well as microcracks. These factors are very useful in precisely quantifying the degree of deterioration of the protective film. In the present work, two types of silicone based paints (silicone‐titanate, rhodorsil silicone) were prepared and the surface degradation of these coatings were studied by EIS technique and SEM with EDAX analysis. The chemical resistance properties were also analyzed.
