Fluorosilicone composite and formulation process for imaging plate

Abstract

An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.
