Effect of amine structure, thermal treatment and stoichiometry on the adhesion Properties of Bio-based Non-Isocyanate Polyurethanes (NIPUs) for footwear substrates

Non-isocyanate polyurethanes (NIPUs) synthesized through cyclic carbonate–amine reactions are emerging as sustainable alternatives to conventional polyurethane adhesives for footwear bonding. In this work, solvent-free NIPU hot-melt adhesives (PHUs) were prepared from diglycerol...
