Patent ID: 8101241

Claim:
A process to form a water-repellant and release coating on a support, the process comprising applying a silicone composition, that is capable of crosslinking by polyaddition, to the support and then crosslinking the silicone composition, wherein the silicone composition comprises as a crosslinking agent, at least one silicone oil comprising at least one hydrogenated PolyOrganoSiloxane (POS) exhibiting, per molecule at least three hydrogen atoms bonded to silicon atoms, and having the following mean linear formula: M α M′ β D γ D′ δ with M=(R 1 ) 3 SiO 1/2 M′=H a (R 1 ) b SiO 1/2 , a+b=3, a=1, 2 or 3, b=0 to 3 D=(R 2 ) 2 SiO 2/2 D′=HR 3 SiO 2/2 0≦α≦2 0<β≦2 0 <γ 0 <δ wherein R 1 , R 2 and R 3 are each a monovalent hydrocarbon group which has no unfavorable effect on the activity of the catalyst and with: 0<γ/δ, 15≦(β/δ)×1000≦150, the POS or POSs having a dynamic viscosity η at 25° C. of less than or equal to 1500 mPa·s, and the support is flexible and is comprised of at least one material selected from the group consisting of polyethylene, polypropylene, polyester, poly(vinyl chloride), polyethylene terephthalate and mixtures thereof, wherein the crosslinking of said silicone composition occurs by placing the support coated with said silicone composition at a temperature of less than or equal to 110° C.
