| abstract |
The invention relates to a curing composition for a fastening synthetic mortar system curable by addition polymerization for mortaring anchoring elements into holes or gaps, wherein the curing composition contains oligomeric siloxanes having, on average per molecule, at least one or preferably two or more organic residues bearing one or more (secondary or primary) amino and/or thiol groups reactive with isocyanate groups or epoxy groups in the addition reaction and having, on average per molecule, at least one or more hydrolyzable groups and can additionally contain one or more further common additives, fastening synthetic mortar systems containing said curing composition. The invention further relates to the use of said fastening synthetic mortar systems for mortaring anchoring elements into holes or gaps, and to manufacturing methods and methods of use for the fastening synthetic mortar systems and the curing composition. |
