process for producing prints based on print organopolisilossani spoons

摘要

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.
