Studies on the properties of silicone resin blend materials for corrosion protection

Studies on the properties of silicone resin blend materials for corrosion protection Purpose – Corrosion protection is one of the important performance properties of organic coatings. The purpose of this paper is to develop a paint system for the protection of steel substrates from corrosion at high temperature atmospheres using silicone resin blend materials. Design/methodology/approach – An anti‐corrosion paint system for high temperature atmosphere has been developed using silicone polyester resins. Silicone resin has been chosen due to its good resistance for corrosion in all kinds of environments. The paint system was prepared from the best performing binder system with the addition of inorganic pigments. Heat stability was studied according to ASTM D2485 standards. Adhesion, impact resistance, film formation, thermal stability and electrochemical properties of the prepared coatings were evaluated by cross hatch adhesion method, tubular impact testing, scanning electron microscopy, differential scanning calorimetry (DSC), and electrochemical impedance spectroscopy (ELS), respectively. Findings – The paint system possessed good adhesion properties and had high‐impact resistance. The SEM graphs showed the uniform formation of the film surface. From thermal analyses, the prepared paint system withstood temperatures up to 400°C. The heat‐treated specimen has also been evaluated for corrosion protection by EIS, which showed high resistance after 30 days of immersion in 3 percent NaCl solution. Originality/value – In this work, an attempt has been made to develop a good paint system using silicone resin and polyester resin blend materials. This research will be useful for the application for high temperature atmosphere and it can give a valuable guidance to the students who are interested in pursuing research in organic coatings. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Anti-Corrosion Methods and Materials Emerald Publishing

Abstract

Purpose – Corrosion protection is one of the important performance properties of organic coatings. The purpose of this paper is to develop a paint system for the protection of steel substrates from corrosion at high temperature atmospheres using silicone resin blend materials. Design/methodology/approach – An anti‐corrosion paint system for high temperature atmosphere has been developed using silicone polyester resins. Silicone resin has been chosen due to its good resistance for corrosion in all kinds of environments. The paint system was prepared from the best performing binder system with the addition of inorganic pigments. Heat stability was studied according to ASTM D2485 standards. Adhesion, impact resistance, film formation, thermal stability and electrochemical properties of the prepared coatings were evaluated by cross hatch adhesion method, tubular impact testing, scanning electron microscopy, differential scanning calorimetry (DSC), and electrochemical impedance spectroscopy (ELS), respectively. Findings – The paint system possessed good adhesion properties and had high‐impact resistance. The SEM graphs showed the uniform formation of the film surface. From thermal analyses, the prepared paint system withstood temperatures up to 400°C. The heat‐treated specimen has also been evaluated for corrosion protection by EIS, which showed high resistance after 30 days of immersion in 3 percent NaCl solution. Originality/value – In this work, an attempt has been made to develop a good paint system using silicone resin and polyester resin blend materials. This research will be useful for the application for high temperature atmosphere and it can give a valuable guidance to the students who are interested in pursuing research in organic coatings.
