Polyurethanes (PUs) and silyl-modified polymers (SMPs) are versatile materials containing both organic and inorganic functional groups, enabling the formation of highly reactive polymer networks. These polymers serve as key components in adhesives, sealants, and coatings, and are widely employed across DIY, construction, and industrial applications for both indoor and outdoor use. The performance properties of PU and SPUR adhesives can be finely tuned through the careful selection of monomers and formulation strategies. However, in most cases, the resulting bonded interfaces are permanent, posing significant challenges for separation and recycling. Developing sustainable end-of-life strategies for these materials remains a critical technical and economic challenge in sectors such as automotive, energy storage, and flexible packaging.
