Development of a Coating System for High Temperature Corrosion Protection

Abstract:

Article Preview

Corrosion protection is one of the important performance properties of organic coatings. In this study, an attempt has been made to develop a high temperature coating. Different compositions of silicone and polyester resins are taken and mixed well with the addition of a hardener. The binder system is applied on the pre-treated cold rolled steel panels. Physical and mechanical properties are evaluated. Thermal resistance of the coating system is done according to specification of ASTM D2485 standards. DSC and TGA analyses are carried out to study the glass transition temperature and temperature dependence of the sample prepared respectively. Corrosion protection ability of the system is evaluated by electrochemical impedance spectroscopy (EIS) and immersion studies. From the thermal studies, the coating containing 40% silicone and 60% polyester has withstood up to 498 K.
