However, a major disadvantage of these adhesives is their low strain recovery, which is problematic for flexible electronics applications. A new study investigates how polyurethane diacrylate (PUDA) as a crosslinker significantly improves the strain recovery of PSAs. The results show that PSAs with PUDA achieve complete recovery from strain significantly faster. While conventional PSAs crosslinked with 1,6-hexanediol diacrylate (HDDA) require a recovery time of about 61 seconds, the strain recovery time of PUDA-based adhesives is only about 2.5 seconds.
