Abstract
Epoxy adhesives are made using core-shell rubbers and small amounts if any of other elastomeric materials. The epoxy adhesives contain a mixture of latent curing agents and/or high levels of calcium oxide. The adhesives exhibit excellent bonding properties even when an open or closed bead is exposed to humid air for prolonged periods before the epoxy adhesive is cured.
