Abstract

Surface treating articles and methods for the manufacture of such articles are provided. The articles of the invention comprise a rotatable core; a plurality of surface treating segments, the segments having first ends adjacent the core and second ends opposite the first ends; and a cured, expanded adhesive composition bonding the surface treating segment to the core, the adhesive composition comprising (a) an organic epoxide compound having an epoxide functionality of at least 1, (b) an epoxide hardener, (c) a film-forming material, and (d) a foaming agent; wherein the expanded adhesive provides a substantially continuous bond area extending from the core into and around the first end of the segments. The method for the manufacture of the articles comprises applying the foregoing adhesive to the core, applying the surface treating segments to the core by positioning the first ends of the segments adjacent the core and in contact with the adhesive; expanding the adhesive into the first ends of the surface treating segments; and hardening the adhesive to form the surface treating article.
