Paper Title:
Hydrogen Bond of Polyaspartic Ester Polyurea Coatings and its Influence on Aging Behavior
  Abstract

Two types of polyurea coatings based on polyaspartic esters (PAE) (PAE-F1 and PAE-F2) were exposed in salt fog environments and outdoor for different time periods. The aging behaviors of two types of coatings were evaluated by using electronic tensile testing machine, glossmeter and Fourier transform infrared spectroscopy (FTIR). The results showed that the salt fog had a significant effect on the gloss loss, hydrogen-bonded urea carbonyl in PAE-F1 and PAE-F2 were 77.1% and 74.9% respectively by the results obtained from FTIR analysis. The index of gloss loss, strength change rate and elongation at break change rate of PAE-F1 and PAE-F2 coatings kept well exposed in outdoor and salt fog environment after 350 days. All test results indicated that PAE coating has excellent aging resistance; PAE-F1 with higher degree of hydrogen bond was more orderly structural and better aging resistant than PAE-F2 coating.
