Patent ID: 7812065

Claim:
A dental impression mass comprising: (A) curable polymers selected from the group consisting of (1) organopolysiloxanes that crosslink by means of an addition reaction, (2) organopolysiloxanes that crosslink by means of a condensation reaction, (3) polyethers containing alkoxysilyl groups that crosslink by means of a condensation reaction, (4) polyethers containing aziridino groups that crosslink by means of an addition reaction, (5) polyethers containing alkenyl groups that crosslink by means of an addition reaction, (6) polyethers containing ester groups of an ethylene-unsaturated carboxylic acid that crosslink by means of a radical polymerization reaction, and (7) polyethers that contain polysiloxanes and/or synthetic rubbers and crosslink by means of a ring-opening metathesis reaction, (B) a non-ionic surfactant with a molecular mass of less than 6000 g/mol containing at least one (poly)alkylene oxide group as well as one silicon-containing group, and (C) a non-ionic fluorosurfactant that has (1) at least one partially fluorinated or perfluorinated hydrocarbon group that is connected with a (poly)alkylene oxide group, a hydrocarbon group, an aliphatic polyhydroxy group, or a heterocyclic group containing nitrogen, by way of an oxygen atom, an amino group, a keto group, a carboxylic acid ester group, a phosphoric acid ester group, a carboxylic acid amide group and/or a phosphoric acid amide group, or (2) at least one partially fluorinated or perfluorinated hydrocarbon group and at least one amino oxide group, wherein the dental impression mass, 40 seconds after the start of mixing, has a low initial water droplet contact angle of <10°, measured at a droplet age of 10 seconds.
