| 摘要 |
Foam forming, self-supporting solidifying composition, for molding biological surfaces, preferably dental composition comprises component (A) comprising at least one molding material based on isocyanate having one or more functional amines and/or hydroxyl group containing compounds abreacting to urethane or urea, A-silicones, C-silicones, polyethers and/or alpha -silanes; and optionally component (B) comprising at least one propellant. Independent claims are included for: (1) an impression spoon, for the composition, comprising an inlet for the formed foam, an unit (2) for sealing the lateral surfaces, and at least one outlet (1) for excess foam, so that the excess foam is not reached in the jaws; and (2) a molding biological surface, from a molding material based on the component (A), comprising closed-porous foam. |
