Abstract:
1. An irradiation-curable silicone-based coating composition, consisting essentially of (a) at least one liquid polyorganosiloxane A having a viscosity of approximately 10 to 10 000 mPa·s at 25° C. and carrying a crosslinkable and/or polymerizable functional group Fa being an epoxy, alkenyl ether, oxetane or dioxolane functional group on at least one M and/or T unit and/or at least one crosslinkable and/or polymerizable functional group Fa on at least one D unit, (b) at least one liquid linear polyorganosiloxane B having a viscosity of approximately 10 to 10 000 mPa·s at 25° C. and carrying 2 crosslinkable and/or polymerizable functional groups Fb being an epoxy, alkenyl ether, oxetane or dioxolane functional group on at least one M unit, said polyorganosiloxane B being composed of units of formula (III) and terminated by units of formula (IV), of formulae: wherein: (1′) the symbols R, which are identical or different, represent: (2′) the symbols Y are identical or different and represent: (c) an effective amount of a cationic photoinitiator composed of at least one onium borate.
