On the other hand, the coating without the need of microcapsules prone to produce the cracks, plus the cracks will continue to expand below the continuous action of environmental things. It’s straight proved that microcapsules can imp of environmental things. It is actually straight 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 following aging tests is usually 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, as well as the characteristic absorption peak of VU0467485 mAChR carbon oxygen absorption peak of OH is at 1731 cm1 , along with the characteristic absorption peak of carbon 1 single bond in ester group is at 1166is at .
