Patent ID: 7423234

Claim:
Process for the surface treatment of an article containing crosslinked silicone, selected from polyorganosiloxanes (POS) crosslinked by the polyaddition of ≡Si—H units onto ≡Si-alkenyl units, obtained from a silicone preparation comprising: at least one polyorganosiloxane (POS) A with ≡Si-alkenyl units, at least one polyorganosiloxane (POS) B with ≡Si—H units, at least one metal catalyst C, optionally at least one POS resin D carrying ≡Si-alkenyl units, optionally at least one crosslinking inhibitor E, optionally at least one adhesion promoter F, optionally at least one mineral filler G, optionally at least one functional additive H for imparting specific properties, wherein: said process comprises spraying at least one plasma jet onto at least part of the silicone surface of said article, the plasma used is a homogeneous atmospheric plasma, and it is carried out continuously by means of a plasma spraying apparatus comprising a rotating head having one or more plasma nozzles that are offset relative to the axis of rotation, each one being capable of generating a plasma jet whose axis is parallel to said axis of rotation.
