Epoxy adhesive having improved low-temperature impact resistance |
| abstract |
A one component epoxy adhesive composition is comprised of, an epoxy resin; a polyurethane based toughener, an epoxy curing agent, and an epoxy capped prepolymer comprised of the reaction product of a polyepoxide and an alkanolamine in which the amine is a primary amine. The epoxy capped prepolymer may be made by mixing and reacting an alkanolamine with a polyepoxide at a stoichiometric excess of the polyepoxide to alkanolamine, wherein said stoichiometric excess has a ratio of epoxides/amino groups is at least 2 to 1 such that the amino groups react whilst the hydroxyls present in the alkanolamine do not. The adhesive composition may give improved impact peel strength while not substantially reducing the elastic modulus. The adhesive may be used to bond metal components in automobile frames and the like. |
