Abstract:
A method of making a repositionable transfer adhesive is provided. The method includes the steps of (a) providing a release liner having opposing first and second surfaces, the first surface having a release value of at least 10 grams per inch, as measured according to the Tape Release Test, lower than the second surface; (b) providing an adhesive composition comprising microsphere adhesive and a binder adhesive; (c) coating the adhesive composition on the first surface of the release liner such that the microspheres protrude from the binder adhesive; (d) drying the adhesive composition to yield a microsphere transfer adhesive; (e) winding the release liner such that the microsphere transfer adhesive is wound inwardly and the second surface of the liner contacts the microspheres; and (f) applying pressure to the second surface of the liner.
