%X The present study was carried out to analyze the performance of anti-corrosion property for the combination of PMMA, resin and ZnO nano particle coating on mild steel in 3.5% NaCl medium at 3hrs, 6hrs and 12hrs exposure. The synthesized nano particle was characterized by FTIR, XRD and SEM analysis. The Polymer +Resin +ZnO (PRZn) combination was coated on MS by dip and spin coating methods. The optimized concentration analyses were verified by visual observation and gravimetric method which were also confirmed by electrochemical studies such as Tafel, AC impedance studies and cyclic voltammetry studies and 10% PMMA and 10% PMMA-resin combination was identified as optimum concentration. So, 10% PMMA-resin combined with 0.1g ZnO was used for further studies and coated on MS and PRZn coating offered almost cent percent corrosion protection of MS upto 12hrs exposure in 3.5% NaCl. PRZn coating was characterized by using FTIR, XRD, Zeta potential measurements and thermal stability was analyzed by thermo gravimetric methods. The high I.E offered by the coating material was due to the presence of major constituents that forms a passive film on the metal surface that protects mild steel from corrosion was identified. Profilometer analysis shows that the thickness and roughness of polymer coated specimen is less than paint coated one. Zeta potential and contact angle measurements of the combination coating material shows a protection against corrosion due to more interfacial tension and reduced size of the particles on the metal surface
