摘要:
A coating for an ink jet printhead front face, wherein the coating comprises a oleophobic low adhesion coating. When the oleophobic low adhesion coating is disposed on an ink jet printhead front face surface, jetted drops of ultra-violet gel ink or jetted drops of solid ink exhibit a contact angle greater than 45° and a low sliding angle of less than about 30°. In embodiments, the oleophobic low adhesion coating is thermally stable wherein the surface contact angle and sliding angle show little degradation after the coating is subjected to high temperatures in a range between 180° and 320° or thereabout and high pressures in a range between 100 psi and 400 psi or thereabout during printhead fabrication and manufacturing.
