Abstract

A multicomponent adhesive composition comprises a composition A and a composition B. Composition A comprises at least one silyl polymer comprising at least one hydrolyzable alkoxysilane group and at least one tackifying resin. Composition B comprises at least one catalyst and at least one compound C chosen from a compound C1 with a number-average molecular mass ranging from 300 g/mol to 500 000 g/mol; and a compound C2 with a vapor pressure at 20° C. of greater than or equal to 0.08 kPa; and mixtures thereof. The composition A:composition B mass ratio ranges from 99.98:0.02 to 60:40. The total content of catalyst ranges from 0.01% to 10% relative to the total weight of said adhesive composition.
