The invention concerns compositions that can be cured in the presence of water or atmospheric moisture comprising at least one polyorganosiloxane having one or a plurality of condensable group(s) or hydrolysable and condensable group(s) and at least one compound capable of catalyzing the condensation reaction of the condensable or hydrolysable and condensable groups of the polyorganosiloxane. This compound is a heterometallic complex of which the chemical formula comprises at least two different metal atoms M and M', M being an atom chosen from the group consisting of the atoms of columns 2 and 13 of the periodic table and M&#x2032; being an atom chose from the group consisting of the atoms of column 4 of the periodic table, and at least one alkoxide or chelating ligand.

Silicone composition that can be cured in the presence of water or atmospheric moisture

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.

The present invention relates to an item having anti-soiling properties and intended for aquatic, and particularly ocean use, and to a method for slowing the growth of aquatic organisms on submersible or semi-submersible structures.

Item having anti-soiling properties and intended for aquatic and particularly ocean use

The present invention concerns a crosslinkable silicone elastomer composition and a method using the composition according to the invention for forming sealing gaskets and assembly seals for the components of a powertrain. The silicone elastomers prepared from the composition according to the invention have:&#x2014;good mechanical strength properties such as shore hardness, breaking strength, modulus at 100% elongation and&#x2014;good resistance to ageing in chemically aggressive fluids such as those used, for example, in a powertrain, in this case engine oils, lubricants for the gearbox and axle, oil/petrol mixtures, coolant liquids, fuels or antifreeze liquids, and&#x2014;good adhesion properties even on surfaces polluted by oils used in a powertrain.

Method and compositions that can be used for sealing and assembling components of a powertrain

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.

Method and compositions for the sealing and assembly of power train components

Coating of flexible materials with liquid compositions is disclosed. The compositions advantageously comprise one or more polyorganosiloxanes crosslinkable by polyaddition, by dehydrocondensation, by polycondensation, cationically or free-radically to form a protective coating or film having, in particular, release and/or water-repellency properties.

A method is described for sealing and assembling components of a drive train by means of silicon elastomers prepared using silicon compositions that do not contain any metal catalyst such as, for example, tin, and cross-linking by polycondensation reactions in the presence of water (for example, ambient moisture).

The present invention relates to a process for producing carboxylic acids. It relates more particularly to a process for producing carboxylic acids by oxidation of a hydrocarbon with oxygen or a gas containing oxygen, and even more particularly to the oxidation of cyclohexane to adipic acid. It relates to a process comprising a step consisting of hydrolysis of the esters formed during the oxidation step.
