This paper mainly studies the glossnesschange、mechanical properties change and hardness change of polyurea coatings during the immersing experiment. The result of the glossness experiment shows that Qtech-116 polyurea sample glossness declining rate were 18.33%, 3.69% and 0.83% after immersed in 5%H2SO4、5%NaOH and 3.5%NaCl for 60d.The mechanical properties results shows that the tensile strengt decrease rate were 16.30%、2.69% and 2.28% after immersed in 5%H2SO4、5%NaOH and 3.5%NaCl for 60d. Qtech-116 polyurea sample hardness showns declined 0.83%、no change and increased 35.81% respectively after immersed in 5%H2SO4、5%NaOH and 3.5%NaCl for 60d.
