The motivation of this study is to investigate the effect of special monomers on purely acrylic resin which affects binder stabilization, surface improvement, corrosion resistance, and mechanical properties of paints. In this study, acrylic binders were synthesized by emulsion polymerization. After optimization, different types of special monomers sodium-allyloxy-2-hydroxypropane sulfonate; 1-methacylamido,2-imidazolidinone ethane; Polypropylene glycol monomethyl methacrylate phosphate ester; and phosphate ester were used respectively with 3% to overall monomer concentration. According to the results, reaction efficiency was the best when the phosphate ester was used as a special monomer. Particle size, solid content, MFFT, glass transition temperature, FTIR spectrum, and viscosity were measured. Finally, purely acrylic resin (AcRe-SM_1) and a purely acrylic resin with phosphate ester (AcRe-SM_6) were added to the paint formulation. The adhesion test was applied according to ASTM 3359 and ISO 2409 Standard. Corrosion resistance performance tests were applied according to ASTM B117 and ISO 9227 standards. It was found that purely acrylic resin with phosphate ester resisted corrosion more than purely acrylic system. Moreover, the adhesion performance of the paint with the resin AcRe-SM_6 was better than the paint formulated with purely acrylic resin.
