  • Thermocurable, one-component, addition-crosslinking silicone compositions
    Patent number: 6251969
    Abstract: Organopolysiloxane particles containing hydrosilylation catalysts (H) and organopolysiloxane (O) and having a particle size of 0.01-10 &mgr;m have, at least in the outermost shell, no glass-transition temperature, softening point or melting point in the range 20° C.-260° C. These organopolysiloxane particles enable the preparation of one-component, addition-crosslinking, thermocurable silicone compositions having a long shelf life.

  • Addition-crosslinked silicone rubbers having a low compression set
    Patent number: 6022921
    Abstract: The mechanical properties of addition-crosslinked silicone rubber are improved when the silicone rubber is brought into contact with a compound (A) having at least one aliphatically unsaturated multiple bond. In particular, the compression set is lowered.
