Abstract
Two-package RTV organopolysiloxane compositions are prepared from storage-stable dihydroxypolydiorganosiloxane aqueous doughs that include an effective water-retaining amount of an alkali metal acrylate and/or methacrylate polymer (hydroretainer); such doughs advantageously contain from 8% to 35% by weight of water.
