Abstract

Silicone polymer although have some exceptional superior properties have limitations when it is exposed to harsh chemicals. Poly Ether Ketone (PEK), a high-performance polymer is well known for its resistance towards acid, alkali and many solvents. PEK exhibits good environmental protection with better thermal stability. In the present study, the coatings were prepared using varying ratios of silicone and Poly Ether Ketone (PEK) to study the effect of concentration of PEK on mechanical, chemical, thermal and performance properties. The clear coatings of Silicone/PEK cured films were characterized for TGA, FTIR and evaluated for thermal resistance, corrosion resistance, resistance to 10% acid, alkali, sodium chloride, detergent solution and humidity resistance. The coating films were found to be stable up to 450 °C as indicated by TGA analysis. It is seen that the performance of silicone / PEK coating films increases with increasing concentration of PEK.
