Composition useful primarily for preparing antifriction varnish, application of this procedure varnish on a support and support so treated silicone.

摘要

Crosslinkable silicone composition, useful especially as a varnish having in particular anti-friction properties, this composition being of the type comprising, on the one hand at least two organosilicon species (A) and (B) reactive with each other in the presence of a catalyst (C) to allow crosslinking, being formed at least one of these two species by one polyorganosiloxane (POS) and, moreover, a particular component (D), characterized: - in that this composition is the type of the crosslinkable by polyaddition; - for the particular component (D) is selected from the group of powders of (co) polyamides -preferably the (co) polyamides 6, 12 and 6 / 12- defined as follows: * particles substantially rounded shape and * Average diameter Phi particle md 0.1 to 200 mum, preferably 5 to 100 m and more preferably still between 10 and 50 mum; - it further comprises at least one particular component (E) selected from the group of silicon powders having an average particle diameter Phi md close to or less than 0.1 m and a BET surface area greater than 50 m 2 / g , preferably between 50 and 400 m 2 / g and especially between 150 and 350 m 2 / g.
