Comparative Studies of Wear and Corrosion Behaviors of Conventional and Nano Filler Based Solvent Free Tarfree Epoxy-amine Coatings

Abstract

Tar-free epoxy coatings aid in protecting intact of Mild Steel (MS) substrate immersion condition of atmosphere. From lot of study revised and assorted that tar free (light colour) epoxy amine coating developed which give better performance for protection in long term. By ASTM method, wear behaviors as well as mechanical properties of quartz (micro silica) and organosiliane (nano silica) based tar-fee epoxy coatings were studied. DETA cured epoxy composites coatings were characterized by FTIR spectroscopic technique, powder X-Ray Diffraction (XRD), SEM and FESEM analysis. Transmission Electron Microscope (TEM) confirmed the size of nano particles. The data of wear index of nano fillers based epoxy coating was observed 8.3mg/1000cycles which indicate such an improvement of of abrasion behavior. Corrosion behaviors of the coated MSspecimens were evaluated by Cathodic Disbondment (CD) test immersion in 3.5% NaCl solution. Water absorption and chemical resistance also studied of composite coatings. All over tar-free epoxy-amine nano composite coating shows good result.
