Abstract:
1. A water-, solvent- and plasticizer-free, one-component parquet adhesive comprising: a) 12 to 36% by mass of a first moisture-reactive, silane-terminated polyalkylene oxide binding agent with an average molecular weight of 6,000 to 20,000 g/mol, wherein silane functions of the first moisture-reactive, silane-terminated polyalkylene oxide binding agent are bonded via alkyl groups to an oligomeric skeletal structure, b) 2 to 18% by mass of a second moisture-reactive, silane-terminated polyalkylene oxide binding agent with an average molecular weight of 300 to 3,000 g/mol, wherein silane functions of the second moisture-reactive, silane-terminated polyalkylene oxide binding agent are bonded via alkyl groups to the oligomeric skeletal structure, c) 30 to 60% by mass of a surface-hydrophobised marble powder with an average particle diameter of 0.8 μm to 4.0 μm, d) 2 to 10% by mass of a surface-hydrophobised chalk powder with an average particle diameter of 0.2 to 0.7 μm, e) 0.1 to 1.0% by mass of a hardening catalyst, f) 0.2 to 3% by mass of a moisture-reactive, silane-modified drying agent, and g) 0.2 to 3% by mass of a moisture-reactive, silane-modified adhesion promoter, wherein a sum of the components a) to g) is from 46.5% to 100%, and wherein the adhesive comprises no non-reactive liquid extenders.
