SINGLE-COMPONENT POLYORGANOSILOXANE (POS) COMPOSITIONS WHICH CROSSLINK TO FORM ELASTOMERS BY MEANS OF POLYCONDENSATION REACTIONS AT AMBIENT TEMPERATURE AND IN THE PRESENCE OF WATER, AND ELASTOMERS THUS OBTAINED |
摘要 |
<p>Single-component silicone compositions which are stable on storage in the absence of moisture and which crosslink by polycondensation reactions catalyzed using a mixed titanium/metal catalyst to give non-yellowing elastomers which adhere to various supports, the reactions being carried out at ambient temperature and in the presence of water; each single-component POS composition comprises: 100 parts by weight of linear diorganopolysiloxane(s) A functionalized at the chain ends by functional group Rfo of alkoxy, acyloxy, iminoxy or enoxy type; 0 to 30 parts by weight of polysiloxane resin(s) B; 0 to 15 parts by weight of crosslinking agent(s) C; 0 to 2 parts by weight of aliphatic alcohol(s) E; 0 to 30 parts by weight of non-functionalized and unreactive linear diorganopolysiloxane(s) F; 2 to 40 parts by weight of inorganic filler G; 0 to 20 parts by weight of auxiliary agent(s) H; and 1 to 150 mug.at (microgram atom) of the metals M1+M2 per 1 g of single-component POS composition, wherein M1 is selected from among titanium, zirconium and mixtures thereof and M2 is selected from among zinc, aluminum, boron, bismuth and mixtures thereof.</p> |
