Abstract

Oligomers wherein phenylalkylsiloxane units comprise at least a portion of the repeating units increase the ability to penetrate porous substrates that is exhibited by crosslinkable liquid organosiloxane compositions containing polyorganosiloxanes when the oligomer exhibits limited compatibility with the crosslinkable polyorganosiloxane(s) present in the curable organosiloxane composition.
