Abstract
The adhesion developed during curing of organosiloxane compositions comprising a polyorganosiloxane containing silicon-bonded alkenyl and fluorinated alkyl radicals, at least one organosiloxane as the curing agent, a platinum-containing hydrosilation catalyst and conventional organosiloxane adhesion promoters is substantially improved when the alkenyl-substituted siloxane units are separated from the closest fluorine-containing siloxane units by at least one dimethylsiloxane unit.
