<p>The curable compositions of this invention comprise a solubilized vinyl-containing fluorosilicone gum, a curing agent for the gum, a platinum-containing hydrosilation catalyst, a treated reinforcing silica filler, and a volatile solvent for the gum and curing agent. The organosilicon compound used to treat the silica filler is critical to obtaining a homogeneous curable composition free of agglomerated particles, and is a hydroxyl terminated polydiorganosiloxane containing silicon-bonded fluorocarbon radicals.</p> |
