Acetal-Functionalized Polyurethane Adhesives: A Path to Debonding-on-Demand

European Polymer Journal
Polyurethanes stand out as remarkably versatile polymers, renowned for their adjustable mechanical and thermal characteristics, making them invaluable across various domains, notably in adhesive applications. Yet conventional polyurethane adhesives typically form permanent bonds, and thus debonding is not possible without harming the bonded substrates.
