Abstract

The invention relates to compositions comprising at least one first and one second component; —the first component K1 comprising at least one di(aminobenzoate) ester A1 of formula (I) with an average molecular weight of 500 g/mol to 2000 g/mol, preferably 600 g/mol to 1500 g/mol and particularly preferred between 650 g/mol and 1300 g/mol, G being a divalent group derived from poly(tetramethylene oxide) diol, and —the second component K2 comprising at least one aromatic polyisocyanate B1 with an average molecular weight of 160 g/mol to 1100 g/mol, preferably 500 g/mol to 800 g/mol.
