Silicone Oil Impregnated Hot Roll
The release property of the silicone elastomer sleeve of a hot roll
xerographic fuser is improved by the addition of a high viscosity polydimethyl
A selected one of commercially available silicone elastomers, such as Dow
Corning 3120 or General Electric CRTV 5206, both of which are generally known
as RTVs, and are generically defined as mixtures o~ hydroxyl terminated
siloxanes, trifunctional alkoxy siloxanes, and inorganic fillers, is mixed with a
small amount of polydimethyl siloxane oil of from 1000 to 60,000 centistokes
viscosity in order to provide the improved release property of the soft hot roll of a
hot roll fuser.
This siloxane oil is added in the amount of about 4 to 6 weight % of the
selected silicone elastomer.
