Abstract
The present invention relates to a silicone composition cross-linkable into elastomer, and to a method which uses the composition of the invention to form joints for sealing and assembling the components of a power train. The silicone elastomers prepared from the composition according to the invention have the following properties: good resistance to aging in chemically aggressive fluids, such as those used for example in a power train, in this case motor oils, gearbox and axle lubricants, oil/gasoline mixtures, coolants, and fuels or antifreeze liquids; good adhesive properties including on surfaces soiled with oils used in power trains; and good mechanical strength properties, such as tensile strength, modulus at 100% elongation, and Shore hardness.
