Dependence of Optical Properties of UV-Curable Sealant on Amount of Catalyst N, N-Dimethylbenzylamine

Abstract:

In the presence of the catalyst N, N-dimethylbenzylamine, a series of ultraviolet-curable sealants 1-6 were synthesized by varying the catalyst amount from 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 part in the process of polymerizing the epoxy resin (25 parts) with acrylic acid (17.5 parts). After having been cured by UV light, the transmittance of equally-thick films of the sealants changed with the amount of the catalyst. Furthermore, we recorded the transmittance of UV-cured sealant films when aged in air at high temperatures. Our results have demonstrated that the amount of catalyst poses limited effects on the transmittance of the synthesized sealants
