Abstract
The present invention relates to a compound of the formula (I) for improving the tensile shear strength of hardened compositions based on silane-modified prepolymers, a composition containing a silane-functionalized prepolymer and a compound of the formula (I), a method for the production of this composition and the use of the compound of the formula (I) in adhesives, sealants, coatings and/or primers, based on silane-functionalized prepolymers and the use of this compound for the production of adhesives, sealants, coatings and/or primers based on silane-functionalized prepolymers.
Claims18
A compound of the formula (I)
- for improving the tensile shear strength of hardened compositions based on silane-modified prepolymers, wherein
- X is selected from the group consisting of —OH, —H, residues with 1 to 12 C atoms, and a substituent —C(═O)—R1;
- R1 is selected from the group consisting of —OH, and residues with 1 to 25 C atoms;
- y=5;
- and
- R2 are residues that are the same or different and are selected from the group consisting of —H, —OH and residues with 1 to 12 C atoms.
A composition containing a silane-functionalized prepolymer and a compound of the formula (I)
- wherein X represents a substituent —C(═O)—R1;
- R1 is selected from the group consisting of —OH and residues with 1 to 12 C atoms;
- y=5;
- and
- R2 are residues which are the same or different and are selected from the group consisting of —H, —OH and residues with 1 to 12 C atoms.
Adhesives, sealants, coatings and/or primers based on silane-functionalized prepolymers comprising the compound of the formula (I)
