ABSTRACT:
This application discloses a composition and a method for catalyzing and crosslinking of a polyepoxy compound and an acrylic resin containing carboxylic acid groups, the catalyst being in the form of a metal chelate, particularly of manganese, zinc or chromium. The compositions, when substantially freed of volatile solvent and adjusted to a viscosity resembling that of gunnable caulking compositions, are particularly well adapted as a replacement for the metallic body solder used in automobile manufacture to fill out imperfections, welded joints and the like, when applied thereto and cured.
