Effect of stabilizer on the storage stability of dure-cure adhesive |
| 초록 |
We prepared a dual-cure adhesive composed of thiol/acrylate/epoxy with improved storage stability. The thiol-acrylate reaction was carried out through photo-curing system, whereas the thiol-epoxy reaction occur in the thermal-curing system. The dual-curing was achieved by photo-curing at 365nm for 3 min and thermal-curing at 90 °C for 30 min. The storage stability of the adhesive was enhanced by applying the stabilizer. We evaluated the storage stability of adhesives according to the content of stabilizer. The viscosity characteristics of the adhesives were observed for 3 days. The structure of the cured adhesives was confirmed at each stage of the curing process by Fourier transform Infrared spectroscopy. The lap-shear strength of the dual-cure adhesive between the two PC films was measured using a universal testing machine. The adhesive using 0.6 wt% of Pyrogallol stabilizer showed the best storage stability and shear strength. |
