    摘要： A process for condensation between at least one ≡SiOH unit and at least one ≡SiOR unit is provided. In accordance with the present invention, R=a hydrogen or a C1-C20 hydrocarbon group optionally comprising one or more heteroatoms, and the ≡SiOH and ≡SiOR units belong to at least one identical or different (organo)silicon compound P. The process is conducted in the presence of an effective amount of at least one catalyst C, comprising a carbene. Compositions are also provided.

    摘要： The present invention relates to a cross-linkable adhesive silicone composition, having a very short cross-linking time and capable of providing an adhesive having mechanical properties sufficient so that it can be used as an adhesive joint and provide waterproofing of a seam joining two substrates. Such a composition comprises: (A) at least a polyorganosiloxane (POSA) having, for each molecule, at least two alkenyl groups, preferably, C2-C6 linked to silicon; (B) at least one polyorganosiloxane cross-linking agent having, for each molecule, at least two hydrogen atoms linked to silicon; (C) a catalytically efficient amount of at least one catalyst containing at least one metallic compound, preferably platinum; (D) a reinforcing mineral filler; and is characterized in that it also comprises at least one polyorganosiloxane (POS A′) gum having a weight content of alkenyl(s) group(s), preferably vinyl(s), between 0.001% and 0.2%, and having a consistency of between 300 and 1200 at 25° C.
