Adhesion Performance and UV-curing Behavior of UV-polymerizable Acrylic Pressure Sensitive Adhesives for Dicing Tape

摘要

The acrylic PSAs were prepared with varying GMA contents and blended with blended with TMPTA from 10 to 30 phr. The curing behavior of PSA blends was monitored by FTIR-ATR. And the T_g of cured films was measured by DSC. The PSA performance was evaluated by peel strength before and after UV irradiation. With these results, the PSA blended with 30 wt% of TMPTA was suitable for dicing tape. These results were also confirmed by RPT that after UV irradiation, the log damping ratio was dramatically changed.
