Abstract

This invention relates to a method for coating the surface of a roll during its manufacture with a chemical agent. ' For example, a fuser roll may have a metallic core plated with one or more layers of various metals or alloys and a final coating of a release agent. Previously, the metal core plated with layers of metals or alloys is rinsed in a series of water rinse baths and dried before the release agent is applied in a separate bath. According to the present invention, the release agent is incorporated into the final rinse bath.

This invention relates to a method for coating the surface of a roll during its manufacture with a chemical agent. ' For example, a fuser roll may have a metallic core plated with one or more layers of various metals or alloys and a final coating of a release agent. Previously, the metal core plated with layers of metals or alloys is rinsed in a series of water rinse baths and dried before the release agent is applied in a separate bath. According to the present invention, the release agent is incorporated into the final rinse bath.

Typically, a release agent may be a silicone fluid such as a mercapto-functional polysiloxane, and it is generally immiscible with water. However, an emulsion of a release agent with water may be obtained by the use of high-speed, high-shear mixers. This emulsion can be added to the final rinse bath or added to the rinse water if a spray rinse is used. After such a final rinse, the coated roll is dried. The drying temperature can be set to evaporate the water and cause a bonding of the release agent onto the surf ace^ of the roll.
