Influence of the Weight Ratio of an Epoxydimethacrylate Oligomer and 1,6-Hexanediol Diacrylate Monomer on Photocrosslinking and Properties of UV-Cured Coatings

Authors: Nguyễn Thiên Vương*, Lê Xuân Hiền*


Influence of the weight ratio of an epoxidimethacrylate oligomer (EDMA) and 1,6 hexanediol diacrylate monomer (HDDA) on photocrosslinking and properties of UV-cured coatings have been studied. The obtained results showed that the decrease of the EDMA/HDDA ratio from 80/20 to 20/80 led to increase of the rate of consumption of acrylate groups upon UV-exposure. Fine coatings on glass and steel CT3 substrates can be easily formed by UV- curable formlations with EDMA/HDDA ratios ranged from 60/40 to 40/60. It was determined that there was obvious diference of the relative hardness of the coatings after 0.3 s of UV-exposure but their investigated properties were similar after 1.2 s of irradiation with gel fraction, swelling degree, relative hardness, impact resistance, flexibility, adhesion and gloss at 60 o of 92 %; 476  457 %; 0.92  0.90; 20  30; 20 mm; point of 5 and 100 %.
