Abrégé
(EN)
A crosslinkable composition is provided including an asymmetric isocyanate, a polyether polyol, and a crosslinker. Polyurethane pressure-sensitive adhesives, articles, and solutions are also provided. The polyurethane pressure-sensitive adhesives have advantageous adhesive properties, low glass transition temperatures, and cohesion following thermal cycling.
