ABSTRACT:
A silicone composition useful especially for the production of varnishes applicable to substrates whose coefficient of friction it is sought to reduce. The object is to provide an anti-friction silicone varnish for textiles coated with silicone elastomers which is economic and adhesive, provides the desired slip, resists soiling and is shiny. This object is achieved by a crosslinkable silicone composition containing two silicones A and B which react with one another in the presence of a catalyst C to allow crosslinking, and a particulate component D selected from the group comprising powdered (co)polyamides—preferably (co)polyamides 6, 12 and 6/12. The (co)polyamide particles are of substantially rounded shape and the mean particle diameter Φmdis between 0.1 and 200 μm, preferably between 5 and 100 μm and particularly preferably between 10 and 50 μm. Also disclosed is a varnishing process and a composite containing the varnished substrate.
