The present invention discloses the use of a polymer chain having at least one carboxylic acid anhydride group as a consistency stabilizer in the base part of a two-part silicone sealant. The base part consists essentially of the consistency stabilizer, 100 parts by weight of a polymeric material having not less than two groups bonded to silicon which are hydroxyl or hydrolysable groups, 5 to 150 parts by weight of filler and, optionally, pigments and/or plasticizers.

Polysiloxane Compositions

Electrically-conductive compositions comprising about 65-85 weight percent of a resin component based on conjugated alkadienes having 4 to 8 carbon atoms and monovinyl-substituted arenes having 8 to 12 carbon atoms, with 10-30 weight percent extra-conductive carbon black, and about 1 to 5 weight percent of at least one lubricant can be molded into video discs without the processing problems encountered with compositions comprising polyvinyl chloride.
