I'm assuming you mean using it as the casting medium, then yes. I've seen a couple of sculpts roughed out in polymer clay, moulded in RTV, then liquid Cx5 poured in. Once cooled, the Cx5 cast is refined/detailed etc t produce the finished master.
Then back into the RTV....
Expensive way to work though!
