Patent ID: 8623170

Claim:
A composition, comprising: i) at least one moisture-reactive silane-functional polymer which is liquid at room temperature; and ii) at least one silane-functional polyester of formula (I): wherein Y stands for an n-valent residue of a polyester P which is solid at room temperature and terminated by hydroxyl groups, after removal of n hydroxyl groups; R 1 stands for a linear or branched, monovalent hydrocarbon residue having 1-12 C atoms, which optionally presents one or more C—C multiple bonds and/or optionally cycloaliphatic and/or aromatic portions; R 2 stands for an acyl residue or for a linear or branched, monovalent hydrocarbon residue having 1-12 C atoms, which optionally comprises one or more C—C multiple bonds and/or optionally cycloaliphatic and/or aromatic portions; R 3 stands for a linear or branched, bivalent hydrocarbon residue having 1-12 C atoms, which optionally comprises cyclic and/or aromatic portions, and optionally one or more heteroatoms; the variable a stands for a value of 0, 1 or 2; the variable n stands for a value of 1-3; A stands for a bivalent residue of a diisocyanate after removal of the two isocyanate groups; the variable q stands for a value of 0 or 1; and X stands for S or for NR 5 wherein R 5 stands for a hydrogen atom or for a linear or branched, monovalent hydrocarbon residue having 1-20 C atoms, which optionally comprises cyclic portions, or for a residue of formula (II): R 6 and R 7 , independently of each other, stand for a hydrogen atom or for a residue selected from the group consisting of —R 11 , —COOR 11 and —CN; and R 8 stands for a hydrogen atom or for a residue selected from the group consisting of —CH 2 —COOR 11 , —COOR 11 , CONHR 11 , —CON(R 1 ) 2 , —CN, —NO 2 , —PO(OR 11 ) 2 , —SO 2 R 11 and —SO 2 OR 11 , and R 11 stands for a hydrocarbon residue having 1-20 C atoms, which optionally comprises one or more heteroatoms, wherein the proportion of silane-functional polyester of formula (I) is 0.5-8 wt % of the total composition.
