IPN structured UV-induced peelable adhesive tape prepared by isocyanate terminated urethane oligomer crosslinked acrylic copolymer and photo-crosslinkable trifunctional acrylic monomer

•A novel IPN structured UV-induced peelable adhesive tape for silicon wafer dicing process was developed with an isocyanate terminated urethane oligomer as cross-linker.•Compared to traditional semi-IPN structured PSA tapes, the adhesion performances of IPN structured UV peelable PSA tape were improved and the remaining adhesive on the wafer after the release of the UV cured tape was greatly reduced.•Both the isocyanate content and molecular weight of the urethane oligomer gave effects on the tape peeling performances.
