Adhesives comprising a silyl-terminated polyether and a tackifying resin provide a considerably reduced tack at relatively slight increases in temperature, undergo purely adhesive failure at such increased temperatures, and have reversible properties (i.e., such properties are substantially retained upon cooling). Such adhesives may be used to reversibly bond a first substrate surface coated with the adhesive to a second substrate surface by adhering the substrate surfaces together at a first temperature; heating the adhesive to a second temperature at least about 20° C. above the first temperature and below the thermal degradation temperature; and separating the substrate surfaces from one another at the second temperature, wherein the adhesive comprises the cured product of a silyl-terminated polyether and a tackifier. Such adhesives may also be cleanly transferred from to a different substrate at such elevated temperatures. Such adhesives may be used for tapes suitable for easy removal at elevated temperatures.
