ABSTRACT:
A composition and method for treating the surface of a metal structure adapted to be used for such purposes as a cornerbead and to have a cementitious material such as a joint compound applied to the surface thereto, the compound and composition and method resulting in the improvement of the adhesion between the surface of the metal structure and the cementitious compound applied thereto, which comprises preparing a composition such as that comprising a forming lubricant for processing the metal structure and a minor proportion of a polyfunctional aziridine incorporated therein. The presence of the aziridine enhances the adhesion properties between the surface of the metal and the cementitious compound even when less highly processed metals and less expensive compounds are utilized.
