Selbsthaftende expandierbare Siliconzusammensetzungen für die Herstellung von Siliconschaum-Verbundteilen

Gegenstand der Erfindung sind selbsthaftende, expandierbare Siliconzusammensetzungen, ihre Herstellung sowie die durch Expansion und Vernetzung erhaltenen Materialien. Crosslinkable compositions containing a crosslinkable organosilicon compound; a silica filler; a silicate or halogen analog thereof, a non-silicate resin-forming monomer; and a solid blowing agent containing intercalated liquid or liquid of crystallization, produce uniform foams of good pore structure, with firm adhesion to substrates, with water repellency and water vapor permeability, and with high elongation and low compression set, and are suitable for use in applications where foamed chloroprene rubber has been used, and in other applications as well.
