    摘要: A coating for an ink jet printhead front face, wherein the coating comprises an oleophobic low adhesion coating having high thermal stability as indicated by less than about 15 percent weight loss when heated to up to 300° C., and wherein a drop of ultra-violet (UV) gel ink or a drop of solid ink exhibits a contact angle of greater than about 45° and sliding angle of less than about 30° with a surface of the coating, wherein the coating maintains the contact angle and sliding angle after the coating has been exposed to a temperature of at least 200° C. for at least 30 minutes. In particular, the coating shows no oil on the coating surface after curing.
