1. A two-component structural adhesive comprising at least the following components,
(i) at least one polyisocyanate having free isocyanate groups and having a content of aliphatically bound NCO groups of 16.0 to 24.0 wt. %, which is substantially free of ester and/or ether and/or carbonate groups,
(ii) at least one amino-functional polyaspartic acid ester of the general formula
![]() in which n=2, and X represents a divalent organic residue obtained by removal of the amino groups from 1, 6-diaminohexane, from 2-methyl-1, 5-diaminopentane or from a linear or branched aliphatic diamine having up to 9 carbon atoms,
wherein R1 and R2 are a methyl or an ethyl group,
wherein the structural adhesive, in the cured state, has a tensile shear strength of at least 7 MPa, wherein the tensile shear strength is measured according to standard DIN/EN 1465 (2009-07) between two test bodies made of roughened V2A steel.
