<p>Fluid, crosslinkable polyorganosiloxane mass comprises: (A) at least a suspension of reinforcing filler in polyorganosiloxane, (B) at least a crosslinking system such as condensation system and addition crosslinking system, (C) at least a corresponding crosslinking catalyst, (D) optionally one or more polar additives, and (E) optionally an additive. Fluid, crosslinkable polyorganosiloxane mass comprises: (A) at least a suspension of reinforcing filler in polyorganosiloxane, (B) at least a crosslinking system such as condensation system and addition crosslinking system, (C) at least a corresponding crosslinking catalyst, (D) optionally one or more polar additives, and (E) optionally an additive (where the suspension is obtained by: mixing polyorganosiloxane (X) or its mixtures with a viscosity, at 23[deg]C, of 100-500000 mPas with water (Y), where the total addition quantity is supplied into the mixture either separately, or partially or totally, also as a component of the condensation-/equilibrium catalyst (Z) or, in adsorbtion condition, over the reinforcing filler (F); optionally maintaining the equilibrium of the mixture at increased temperature (preferably 50-180[deg]C) for 15-120 minutes; supplementing (F) with a specific surface (Brunauer-Emmett-Teller) of at least 40 m2>/g; reacting in increased temperature (preferably 50-180[deg]C); deactivating (Z) by supplementing one or more deactivating agent (DA); separating the volatile components by baking in an inert gas stream and/or under reduced pressure at 80-180[deg]C; and optionally supplementing a further polysiloxane (XX) or its mixture). An independent claim is included for the preparation of fluid, crosslinkable polyorganosiloxane mass.</p> |
