Abstract: The present invention provides an acrylic-epoxy hybrid two part adhesive composition for structural metal bonding such as closure hem flange bonding in an automotive line. The new composition offers several performance benefits over the current commercially available adhesive compositions in that it is pre-curable by induction. The new composition has high static and dynamic strength after passing the e-coat oven on oily metal surfaces with reduced failure mode and provides bubble-less adhesion to electro-galvanized coated steels. The new composition also has good initial strength values if cured at room temperatures only.

Abstract: The invention is an epoxy resin system useful as an adhesive for high temperature applications. The system is a combination of a diglycidyl ether a bisphenol epoxy resin(s), at amounts of 30-70% by weight, with 1-10% by weight of an epoxy novolac resin 10-30% by weight of a polyurethane toughener which preferably has the terminal isocyanate functional group blocked,1-8% by weight of a hardener, 0.1-% by weight of a cure accelerator, preferably a latent urea cure accelerator, provides the desired balance of mechanical strength and elastic modulus. The epoxy novolac resin is characterized by at least one of the following features: (i) having a viscosity at 25 degrees C of less than 3000 mPa-s according to ASTM D-445, (ii) an average number of epoxide groups per molecule of more than 2 but less than 3.7, and (iii) a molecular weight of less than 750 g/mol.
