In the study organic-inorganic hybrid composite, epoxy modified silicone coating and vinyl ester flake mas-tic were comparatively used as several anti-corrosion materials that provided protection for flue gas desulfu-rization (FGD). The relationship between curing conversion rate of hybrid polymer and temperature was in-vestigated by differential scanning calorimeter (DSC). The adhesion strength, coefficient of thermal expan-sion and flame retardant properties of three anti-corrosion materials were measured and analyzed. A corro-sion test in 8% H2SO4 and 5% HCl at temperature cycle of 40˚C ~ 160˚C was applied to study corrosion re-sistance of several anti-corrosion materials. Gravimetric measurement and morphological observation of three materials before and after corrosion test were comparatively analyzed in the paper. The small weight change and good morphological structure of hybrid composite during corrosion test demonstrate that hybrid composite has better anti-corrosion properties than epoxy modified silicone coating and vinyl ester flake mastic.
