Abstract
A polyurethane adhesive is prepared from a reaction mixture containing small amounts of chain extender material and a high equivalent weight of a polyol and a monoalcohol. An article adhered to a substrate using this adhesive is firmly affixed to the substrate, yet can be removed without leaving residual adhesive on the substrate. In addition, this adhesive can be washed and reused if desired.
