Acrylate structural adhesive

An amine-free, two-component system of reduced odor of a

• (i) first component comprising a (meth)acrylic acid, a C1-6-alkyl (meth)acrylate, a hydroxy-C1-6-alkyl (meth)acrylate, and additionally
• a cycloalkyl (meth)acrylate, and/or
• a glycolether (meth)acrylate according to general formula (I),
• CH2=CR—C(═O)—O—[CH2CH2-O]n-CmH2m+1, (I),
• wherein R is —H or —CH3;
• index n is an integer within the range of from 1 to 12;
• and index m is an integer within the range of from 1 to 8;
• and
• (ii) a second component comprising a peroxide polymerization initiator;
• wherein the first component and/or the second component additionally comprise a liquid first toughening agent;
• a solid second toughening agent differing from the first toughening agent;
• a first core shell impact modifier;
• and optionally, a second core shell impact modifier differing from the first impact modifier;
• wherein the first component and the second component are spatially separated from one another;
• and
• wherein the reaction of the first component and the second component after mixing results in a structural adhesive.
