    Abstract: PROBLEM TO BE SOLVED: To provide a thermosetting structural epoxy adhesive having excellent storage stability.SOLUTION: The following compound is used as a reinforcement. The compound comprises an elastomeric prepolymer residue selected from the group of a polyurethane, a polyurea and a polyurea polyurethane having isocyanate end groups. The isocyanate end groups of the prepolymer residue are capped by a capping compound selected from the group consisting of a primary aliphatic, cycloaliphatic, heteroaromatic and aromatic aliphatic amine, a secondary aliphatic, cycloaliphatic, aromatic, heteroaromatic, and aromatic, aliphatic amine, a thiol and an alkyl amide. The capping compound is bound to the end of the polymer chain of the elastomeric prepolymer in such a manner that the end to which it is bonded no longer has a reactive group.

    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: A heat-curable structural adhesive includes a non-rubber-modified epoxy resin, a reaction product of a carboxyl- or amine-terminated butadiene polymer or copolymer and a bisphenol F-based epoxy resin, a elastomeric toughener containing capped isocyanate groups, one or more epoxy curing agents a moisture scavenger and a heat activatable catalyst comprising a mixture of a solid or liquid tertiary amine compound that has a boiling temperature of at least 130°C and a novolac resin. The structural adhesive develops excellent bonding properties when cured at moderate temperatures, especially from 120 to 170°C, and in addition performs very well in environmental aging stress testing. The adhesive is particularly good for bonding aluminum to another metal, or bonding aluminum to aluminum.
