Nonetheless, the coating without the need of microcapsules prone to generate the cracks, along with the cracks will continue to expand below the continuous action of environmental things. It is actually directly proved that microcapsules can imp of environmental components. It’s directly proved that microcapsules can enhance the aging resistance thermal stability of waterborne coatings. resistance and and thermal stability of waterborne coatings.Figure 12. 12.

The characteristic absorption before and soon after aging tests could be observed in Figure 15. The characteristic absorption peaks of methyl and methylene are at 2943 cm1 and 2875 cm1. The characteristic absorppeaks of methyl and methylene are at 2943 cm1 and 2875 cm1 . The characteristic tion peak of OH is at 1731 cm1, and also the characteristic absorption peak of carbon oxygen absorption peak of OH is at 1731 cm1 , as well as the characteristic absorption peak of carbon 1 single bond in ester group is at 1166is at .
