Patent ID: 7186758

Claim:
A two-component addition-crosslinking silicone impression material comprising a first component and a second component, wherein the material, when the two components are in the mixed state, comprises: (a) from 1 to 35% by weight of a mixture of at least one organopolysioxane having at least two unsaturated groups in the molecule and having a viscosity in the range of from 25 to 500 mPa*s at 25° C., and at least one organopolysiloxane having at least two unsaturated groups in the molecule and having a viscosity in the range of from 60,000 to 500,000 mPa*s at 25° C., (b) from 1 to 10% by weight of at least one organohydrogenpolysiloxane having at least two SiH groups in the molecule, (c) from 0.00005 to 0.05% by weight of at least one platinum catalyst, calculated as elemental platinum, (d) from 4 to 10% by weight of at least one liquid paraffin or at least one white mineral oil or of a mixture consisting of at least one liquid paraffin and at least one white mineral oil, (e) from 50 to 90% by weight of at least one filler, in each case based on the total weight of the silicone impression material, with one of the components exhibiting, prior to being mixed with the other component, a Brookfield viscosity in the range from 800 to 2000 Pa*s at 23° C., characterized in that, in the mixed state, the silicone impression material exhibits a consistency of less than or equal to 35 mm, as determined in accordance with ISO 4823.
