<p>Tin-free, single-component silicone compositions which are stable with respect to storage in the absence of moisture, and which can be crosslinked into an elastomer by means of polycondensation reactions at ambient temperature and in the presence of water; such elastomers are adherent on various supports and harden rapidly and the silicone compositions contain an alkoxy-functional polyorganosiloxane (POS), a carboxylic acid and/or a carboxylic acid anhydride, and, optionally, a mineral filler of fumed silica type, an alkoxy-functional POS resin and an organometallic compound (containing no tin).</p> |
