摘要： 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).
