A plateau of healing efficiency is observable for each of the coatings. For the coatings n five to 7, the plateau of healing efficiency is reached right after two h of heating. Just after this duration, It is observable that the heating duration significantly impacts the n 1 may be the self-healing efficiency varies within the regular deviation value.

In to observe self-healing on these acrylate coatings. In addition, the limit of those self-healing healing efficiency stagnates about 50 . coatings is five abrasion cycles. Upon this point, the abrasions had been too deep to become repaired. After varying the abrasion cycles as well as the healing parameters (time and heating The hypothesis is the fact that some polymer is removed from the coating throughout abrasion, so temperature), it could be concluded that heating for two h at 80 would be the optimum setting to hydrogen bonds cannot be rebound.HEMA – Ebecrylobserve self-healing on these acrylate coatings. Moreover, the limit of those self-healing coatings is five abrasion cycles. Upon this point, the abrasions have been too deep to be repaired. The hypothesis is the fact that some polymer is removed in the coating through abrasion, so hydrogen bonds cannot be rebound.
