  • Curable organopolysiloxane compositions with improved adhesion
    Patent number: 4082726
    Abstract: This invention relates to curable organopolysiloxane compositions which have self-adhering properties. The self-adhering properties eliminate the need of priming substrates with adhesives or coupling agents. These compositions give better adhesion to substrates than the same organopolysiloxane without the adhesive component but which are adhered using primers.
