Abstract
The present invention relates to a composition, preferably for bonding together metal sheets, comprising: a. 1 part by mole of at least one linear epoxy resin with an average epoxy equivalent weight of 600 to 5,000 g/mole and an epoxy functionality of 2, b. 0.4 to 0.8 parts by mole of at least one non-linear epoxy resin having an average epoxy equivalent weight of 180 to 350 g/mole and an average epoxy functionality of at least 3, c. 0.8 to 1.3 parts by mole of at least one basic hardener comprising at least two free amine-bonded hydrogen atoms, and d. 0.9 to 1.2 parts by mole of at least one crosslinker comprising at least two blocked isocyanate groups.
