Study on the photocrosslinking of the photocrosslinkable system based on epoxy resin modified by tung oil. V - Study on the photocrosslinking of the photocrosslinkable system ETT-39-HDDAI-184-TAS

Abstract

The photocrosslinking of the coating on the base of epoxy resin modified by Tung oil (EIT39), Hexanendiol diacrylate (HDDA), photonitiators of radical and cationic polymerization 1.l84 and TAS with mass ratio ETT39/HDDA/I.184/TAS = 50/50/3/1 ¸ 5 have been studied. The fastest rate of the photopolymerization of the both acrylat, epoxy groups and their highes value of final conversion observed containing. When the content of TAS was 5% of the total contents of ETT39 and HDDA leading to the formation of a UV-cured coating with good phisico mechanical properties
