Abstract | The present invention relates to fuser release agents or fusing oils useful in fusing subsystems in electrostatographic, including digital and color, apparatuses. In embodiments, the release agents comprise a fluorosurfactant, which is useful in compatibilizing the dissimilar materials in a release agent, and for reducing surface tension between the liquid release agent and the solid surface of the fuser member. In embodiments, the fluorosurfactant comprises pendant acid or ester groups. In other embodiments, the fluorosurfactant contains pendant olefin groups. In still yet another embodiment, the fluorosurfactants contain pendant silane groups. In other embodiments, the fluorosurfactants contain pendant alcohol groups. In embodiments, the release agent comprises a silicone oil, and in specific embodiments, a polydimethylsiloxane oil. In embodiments, the silicone release agent may or may not contain functional groups.
A release agent having a polydimethylsiloxane and a fluorosurfactant other than a silicone glycol polymer, a perfluoroalkylsubstituted polyethylene glycol, or a perfluoroalkylsubstituted silane. |
