Some organic resins novolac,furan and epoxy were blended with inorganic additives Ti O2, CaCO3, Talc, Zn dust and Sintered glass. These materials were formulated to produce ten formula designated fromF10-F100. The toluene diisocyanate (TDI) was used as curing agent at different ratios 5, 10, 15 and 20 parts. The carbon steel alloy specimens were provided fromunused petroleum pipelines. The surfaces of specimens were prepared by polishing with different grade emery paper. The visual inspection, physical, mechanical and chemical properties such as, wet film thickness (WFT), dry filmthickness (DFT), adhesion forces, bending, impact, hardness and thermal stability at 50 - 500 ºC at intervals of 50 ºC were studied and discuses. Effect of organic solvent for 72 days, methylethylketon, chloroform, acid effect (10% H2SO4) at period time of 50 days and salt spray tests effect at period time of 21 days for the formed dry filmswere studied. The surfaces of films were visual inspected by magnification power after chemical tests. Electrochemical for formed dry films were studied and indicated. The surface morphology of formed dry films before and after electrochemical tests were exanimate by scanning electron microscope (SEM). The results indicated that the corrosion spots did not detect on the surface of the formed dry films. These films approved to be a protections agent for the surface of petroleum equipments against corrosion.
