Patent ID: 7198854

Claim:
A crosslinkable silicone composition useful especially as a varnish which has anti-friction properties, said composition comprising at least two organosilicon species A and B which react with one another in the presence of a catalyst C to allow crosslinking, at least one of these two species comprising a polyorganosiloxane (POS), and at least one particulate component D, wherein: this composition is crosslinkable by polyaddition; the particulate component D is selected from the group consisting of powdered (co)polyamides defined as follows: the particles are of substantially rounded shape, and the mean particle diameter Φ md is between 0.1and 200 μm; it also contains at least one other particulate component E selected from the group consisting of powdered silicas having a mean particle diameter Φ md of about 0.1 μm or less, and a BET specific surface area greater than 50 m 2 /g.
