제목 Solvent free dual-cure adhesives with epoxy acrylate oligomer using carboxylized monomer
초록 Dual-cure adhesives have a composition that can be cured by a separate curing method with different bonding mechanism. We synthesized a novel epoxy acrylate (EA) oligomer using carboxylized monomer and applied it to a thiol/acrylate/epoxy adhesive system to investigate the characteristics of dual-cure. We suggested a mechanism for EA synthesis and photo/ thermal dual-cure. We confirmed the structure of the synthesized EA using FT-IR and NMR spectroscopy. Furthermore, we measured lap-shear strength and peel strength according to molar ratio of EA oligomer and thiol/acrylate/epoxy using a universal testing machine. The adhesion properties of dual-cure adhesives using EA oligomers were observed to be superior to those of dure-cure ones using commercial EA oligomer. In addition, storage stability of dure-cure adhesives according to the content of the stabilizer and gel fraction of dual-cure adhesives were evaluated.
