Abstract
The invention concerns a radiation-curable silicone coating based on silicones having a viscosity not more than 1500 mPa's, radiation-curable, comprising: (a) at least a liquid polyorganopolysiloxane polymer Pa with viscosity higher than 500 mPa's and having at least a terminal unit of formula [Z—Si (R1)(R2)—O—] (I), and (b) at least a polyorganopolysiloxane Pb, with viscosity less than 150 mPa's and having at least a unit of formula (I) defined above and/or at least a unit of type D of formula —[—(Si(R1)(Z)—O—]— (ii), Z being a crosslinkable and/or polymerizable group; (c) at least an efficient amount of at least an initiator consisting of onium borate.
