Curable organosiloxane compositions of extended shelf life and cured elastomers therefrom exhibiting extended mold life

摘要

Curable organosiloxane compositions, comprising a silanol-containing polyorganosiloxane; an organosilicon compound containing at least three silicon-bonded hydrolyzable groups per molecule; a tin catalyst; and a polybutene fluid are claimed herein. They exhibit extended shelf life and yield, upon cure, an elastomer exhibiting extended mold life.
