The present invention relates to a moisture-crosslinkable sealant composition comprising:

Polyimines and uses thereof

The present invention relates to a method for producing a composition comprising at least one polyurethane with NCO end groups, and at least one catalyst B selected from among tertiary amines, said method comprising the following steps: a) production of a polyurethane with NCO end groups, comprising a step of polyaddition of a polyol composition and a polyisocyanate composition, in the presence of at least one catalyst A selected from the group consisting of—organo-metallic catalysts excluding tin-based catalysts, —tertiary amines, and—mixtures of same; and b) the addition of at least one catalyst B, selected from among tertiary amines, to the polyurethane with NCO end groups obtained in step a).

Method for producing a composition comprising a polyurethane with NCO end groups

Adhesive sealant composition comprising at least one moisture-crosslinkable prepolymer and, as plasticizing agent, an ester compound of formula (I): in which:
