The invention relates to moisture-hardening hot-melt adhesives for instantaneously processing bonded substrates containing reaction products obtainable by the reaction of bifunctional- and/or multifunctional (poly- )isocyanates with hydroxyl polyesters based on polyols and dicarboxylic acids. According to said invention, the dicarboxylic acid is embodied in the form of a linear aliphatic dicarboxylic acid containing from 13 to 22 methylene groups.
L'invention concerne des adhésifs thermofusibles réticulables à l'humidité pour l'usinage immédiat des substrats collés. Les adhésifs thermofusibles selon l'invention contiennent des produits issus de la réaction de (poly)isocyanates bifonctionnels et/ou multifonctionnels avec des polyesters d'hydroxyle à base de polyols et d'acides dicarboxyliques. Selon l'invention, on utilise comme acide dicarboxylique un acide dicarboxylique aliphatique linéaire ayant 13 à 22 groupes méthylène.
