Abstract

The invention relates to silicone compositions that are used in the production of varnishes that can be applied to supports in order to reduce the friction coefficient. The inventive composition comprises at least one polyorganosiloxane A (POS) which can be cationically and radically cross-linked by functional cross-linking groups (GFR) and a primer C chosen from onium borates, characterized in that the inventive composition also comprises molecules (POS D) which are substituted by secondary functional groups (GFS) carried by silicon atoms and selected from those that include at least one alkoxy and/or epoxy and/or carboxy motif and optionally a charge (e.g. silica). The invention can be used with anti-friction varnishes for RTV silicone coatings for material used in air bags, thermal transfer ribbons or packing films.
