Abstract
Impression compositions containing (a) an organopolysiloxane having at least two alkenyl groups and containing at least 20 mol percent of monoorganosiloxane units, (b) an organopolysiloxane having at least 3 Si-bonded hydrogen atoms per molecule, (c) a catalyst which promotes the addition of Si-bonded hydrogen atoms to alkenyl groups and (d) 30 to 90 percent by weight of a filler, based on the total weight of the composition. Impressions are obtained by applying a composition containing components (a), (b), (c) and (d) to a surface of which an impression is to be made, crosslinking said composition and thereafter removing the formed structure from the contacted surface.
