Abstract

A room temperature curable sealant/adhesive composition is disclosed. The room temperature curable sealant/adhesive composition comprises: A) one or more organopolysiloxanes; B) a hydrophilic material; C) a cross-linker; D) a titanate catalyst and/or a zirconate catalyst; and E) one or more optional ingredients. A silicone elastomer formed therefrom and related methods are also disclosed. In general, such compositions (upon several hours of contact with water) do not repel water, but rather retain and pick-up water and/or can be wetted by aqueous materials subsequent to exposure.
