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 siloxane oil.

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.
