Abstract
The present invention relates to an organopolysiloxane composition, containing a cyclopentenyl radical, which is stable on storage in the absence of gaseous oxygen, in particular in the absence of atmospheric oxygen, and is crosslinkable to an elastomer in the presence of gaseous oxygen, originating in particular from the atmosphere, characterized in that it comprises: PA1 (A) 100 parts of diorganopolysiloxane containing at least 3 cyclopentenyl radicals per molecule, each of these groups being directly linked, by a SIC bond, to a different silicon atom, PA1 (B) a catalytically effective amount of a hardening catalyst and PA1 (C) 0 to 250 parts of an inorganic filler. Application of the compositions to the production of coatings or of seals.
