  • Patent number: 8010033
    Abstract: A fuser component useful in electrostatographic machines is provided, having a substrate, and thereover a coating composition comprising a haloelastomer, such as, for example, a fluoroelastomer, and a deflocculating agent. A fuser component comprising a deflocculating agent exhibits improved properties including, but not limited to, increased gloss and a smoother coating surface with a relatively high adhesive strength. The use of a deflocculating agent also reduces or eliminates the barium sulfate defect.

  • Patent number: 7342227
    Abstract: A plasma sprayed TiO2 coating is used to remove effluents produced during an electrical charging step using a corona charging device. The plasma spray allows for the application of TiO2 ceramic to an aluminum dicorotron housing. Plasma spray also increases the electrical conductivity of the TiO2 (which is necessary for the dicorotron operation). Plasma sprayed coatings are also porous which aids in the capture and reduction of effluents.
