Abstract
The present invention relates to a cross-linkable, elastomeric silicone composition and to a method using the composition according to the invention to form seals for sealing and assembling components of a power train. The silicone elastomers prepared from the composition according to the invention have: good resistance to ageing in chemically aggressive fluids such as those used e.g. in a power train, in this case engine oils, gearbox and axle lubricants, oil/gasoline mixtures, coolants, fuels, or antifreeze; good adhesion properties, even to surfaces soiled by the oils used in a power train; and good mechanical-strength properties, such as breaking strength, elongation at break, and Shore hardness.
