    摘要: The invention relates to epoxy adhesives. An epoxy adhesive is provided that simultaneously has low E-modulus and high glass temperature. Such adhesives are useful in the manufacture of large machinery (e.g., automobiles), and are useful for bonding different materials, such as metal and carbon fiber composite. The cured epoxy adhesive can be formulated to have an E-modulus of less than 1000 MPa, and a glass transition temperature of at least 80 C. The epoxy adhesive comprises a capped polyurethane pre polymer, a core shell rubber, and polyetheramine-epoxy adduct.

    摘要: 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.
