NON-DRIP SILICONE ELASTOMER COMPOSITION, CROSSLINKABLE BY POLYADDITION, AND ITS USES FOR MAKING JOINTS IN SITU AS ADHESIVE IN PARTICULAR IN SADDLERY |
摘要 |
A non-drip, preferably self-adhesive, silicone elastomer composition crosslinkable by polyaddition, such as those polyorganosilanes (POS) bearing C<SUB>2</SUB>-C<SUB>6</SUB>≡Si-alkenyl units and ≡Si-H units but excluding fluorinated POS. The composition includes at least a thixotropic additive containing at least a fluorinated resin, preferably based on polyfluoroethylene (PTFE). The composition may be prepared from a Si-Vi polydimethylsiloxane (PDMS) and a Si-H PDMS crosslinked by platinum catalysis. Polytetrafluorethylene, a filler, particularly one containing silicone, optionally a ternary adherence promoter such as vinyltrimethosilane/glycidoxypropyltrimethoxysilane/butyl orthotitanate, and other typical additives may be added to the composition. The composition (not excluding the fluorinated POS as a possible constituent in the composition) may be used to produce joints in situ and/or as an adhesive, particularly in upholstery. |
