Patent ID: 8247482

Claim:
A composition comprising: at least one (poly)isocyanate; at least one surfactant comprising an amine based on the following formula (III-1): in which: a is equal to 0, 1 or 2; R 7 represents a hydrogen atom or a hydrocarbon chain; and when a=0 the R 7 groups may be the same or different and may optionally form a cyclic structure comprising from 3 to 5 carbon atoms; R 6 and R′ 6 are identical or different and represent a hydrogen atom or a hydrocarbon chain; k represents an integer greater than or equal to 1; k′ represents an integer from 0 to 60; L 1 and L′ 1 are the same or different and represent, independently, a radical of formula -[-L′-O—] t —, t being an integer from 0 to 20, L′ being a linear or branched alkylene radical comprising from 3 to 10 carbon atoms, L′ groups being the same or different; and L 2 and L′ 2 are the same or different and represent, independently, a linear or branched divalent alkylene radical and a mixture of compounds based on the following formulae (I-1) and (II-1): in which: R 1 and R 2 are the same or different and represent, independently, a hydrocarbon chain optionally substituted; said mixture of compounds of formulae (I-1) and (II-1) being characterised in that the molar ratio of compound (II-1) to compound (I-1) is greater than 1 wherein at least one compound carrying at least one mobile hydrogen function is selected from the primary or secondary hydroxyl, phenol functions, primary and/or secondary amine functions, carboxylic functions and SH functions, and from 0% to 30% by weight organic solvent, relative to the total weight of the composition.
