제목 Effect of functional group ratio ([OH]/[NCO]) on long-term reliability of polyurethane pressure-sensitive adhesives (PU-PSA)
초록 Polyurethane pressure-sensitive adhesives(PU-PSA) with high durability and removability were achieved through various polyols, isocyanates, and additives studies. To estimate PUs synthesized with control of mole ratio of Hydroxyl group/Isocyanate group ([OH]/[NCO]), degree of crosslinking was analyzed through reduction of NCO group peak in Fourier-transform infrared (FT-IR) spectroscopy and long-term reliability of PSA calculated by WLF (Williams-Landel-Ferry) equation. The thermal properties and structures of the fabricated PU-PSAs were analyzed by differential scanning calorimetry (DSC) and FT-IR spectroscopy. One hundred eighty degree peel tests by universal testing machine (UTM) were used to evaluate mechanical peel properties of PU-PSAs.
