Abstract:
(EN) The invention relates to a method for producing an object from a construction material, the construction material comprising radically crosslinkable groups, NCO groups and groups having Zerewitinoff active H atoms, and the object being a three-dimensional object and/or a layer. During and/or after the production of the object, the construction material is heated to a temperature of > 50°C, and the construction material comprises one or more cyclic tin compounds of formula F-I, F-II and/or F-III:
(FR) L'invention concerne un procédé de fabrication d'un objet en un matériau de construction, le matériau de construction comprenant des groupes réticulables par réticulation radicalaire, des groupes NCO, ainsi que des groupes comportant des atomes de H actifs selon Zerewitinof, l'objet étant un objet tridimensionnel et/ou une couche. Pendant et/ou après la fabrication de l'objet, le matériau de construction est chauffé à une température > 50 °C, et le matériau de construction comprend un ou plusieurs composés cycliques de l'étain de formule F-I, F-II et/ou F-III.
(DE) Ein Verfahren zur Herstellung eines Gegenstands aus einem Aufbaumaterial, wobei das Aufbaumaterial radikalisch vernetzbare Gruppen, NCO-Gruppen sowie Gruppen mit Zerewitinoffaktiven H-Atomen umfasst und der Gegenstand ein dreidimensionaler Gegenstand und/oder eine Schicht ist. Während und/oder nach der Herstellung des Gegenstands wird das Aufbaumaterial auf eine Temperatur von > 50 °C erwärmt und das Aufbaumaterial umfasst eine oder mehrere zyklische Zinnverbindungen der Formel F-I, F-II und/oder F-III:
