  • Publication number: 20080019743
    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.
