Abstract (en)
[origin: WO2022195235A1] The present invention concerns a two-component adhesive composition comprising an -OH component and an -NCO component and characterized in that: - the -OH component is a composition comprising at least one polyol A1; 1 - the -NCO component is a composition comprising at least one polyurethane P2 obtained by a process comprising the following steps: S1) preparing a polyurethane prepolymer P1 comprising at least two terminal -NCO functions by a polyaddition reaction: i) of at least one polyester polyol A2 having a number-average molecular mass (Mn) of from 8000 to 12 000 g/mol; ii) of at least one polyol A3 having a molar mass of not more than 200 g/mol, said polyol A3 comprising at least one secondary OH function; iii) of at least one polyisocyanate; iv) of an optional polyol A4; in amounts such that the molar ratio NCO/OH (r1) is from 1.7 to 2.2; and S2) reacting the product formed at the end of step S1) with at least one aminosilane, in amounts such that the molar ratio NCO/NH (r2) is from 10 to 25.
