Synthesis and properties of UV-curable sealant for LCD panels

扫码查看
Ultraviolet curable sealant was synthesized by polymerizing epoxy resin with acrylic acid in the presence of catalyst N,N-dimethylbenzylamine. The synthesized ultraviolet-curable sealant could be solidified upon exposure to 365 nm ultraviolet irradiation for 8 seconds. The optical, mechanical and thermal properties of the ultraviolet-cured sealant were investigated with ultraviolet-visible spectrometer, tensile machine and differential scanning calorimetry, respectively. Our results demonstrated that the transparent and thermally stable sealant was strong enough for liquid crystal display panels.
