Acrylic pressure sensitive adhesives (PSAs) are widely used in various industrial applications. However, higher thermal stability of PSAs is needed especially for the recent semiconductor manufacturing processes. In this study, crosslinking was employed to improve the thermal stability and mechanical properties of acrylic PSA. UV-curing of PSAs was carried out by using triallyl isocyanurate as the crosslinking agent and photo initiator. A series of crosslinked acrylic PSAs were prepared with various gel fractions. The crosslinked acrylic PSA were characterized by Fourier transform infrared spectroscopy. The adhesion performance of acrylic PSA was investigated by measuring the peel strength, gel content, and dynamic mechanical analysis. The thermal properties of acrylic PSAs were evaluated by differential scanning calorimetry, thermogravimetric analysis, and thermomechanical analysis. |
