Abstract
A novel composition for use as a print head face plate coating. In particular, the coating comprises siloxyfluorocarbon (SFC), which is composed of networked precursors containing reactive siloxane groups attached to fluorocarbon chains. The present SFC coatings can be used to produce a surface whereby solid ink and ultraviolet (UV) curable inks do not adhere when applied at elevated temperatures and over an extended period of time. The advantages of the present coating are fewer print head related defects, and longer front face life.
