Abstract

Recent developments indicate that the polymer coatings used to protect steel structures from corrosive environments are rarely one-component systems. Polymeric blends used to protect the structures are a mixture of atleast two polymers or copolymers. The heterophase polymer blends are known as polymer-polymer composites (PPC). The advantages of PPC coatings in comparison to multicoat system are high thickness per coat, excellent protection and superior layer adhesion. Presents a study in which a poly (epoxy-chlorinated rubber-silicone) PPC coating was prepared and its chemical resistance properties in acid, alkali and neutral solutions were studied. Different combinations of these three binders were also prepared in toluene:acetone solvent mixture and the chemical resistance properties of these PPCs were evaluated in comparison with the corresponding multicoat system with the same thickness. Finds that the PPCs show superior properties when compared to multicoat systems. Studies the electrochemical behaviour such as potential, resistance and capacitance of the PPCs and the multicoat systems on steel
