“…Free (non-hydrogenbonded) N-H group vibrations at approximately 3,400-3,500 cm -1 are weakly observed, indicating that most N-H groups of GWPU are involved in hydrogen bonds. The absorption bands at 2,800-3,010 and 2,792 cm -1 correspond to C-H stretching vibrations and O-CH 2 stretching, respectively [29]. The bands assigned to stretching vibrations of the carbonyl in urethane groups appear at around 1,725 cm -1 .…”

“…The majority of reactive hot melt adhesives (RHAs) are moisture curing polyurethane (PU) adhesives whose main component is an isocyanate-terminated polyurethane prepolymer that can be cured after application by reaction with ambient moisture [1][2][3][4][5][6][7][8] . These adhesives are applied in molten form, solidify upon cooling, and are subsequently cured by reaction with ambient moisture.…”
