Claim:
1. A process of forming an oleophobic low adhesion coating for an ink jet printhead front face, comprising: mixing a reactant mixture comprising a first isocyanate compound and a hydroxyl functionalized fluoro-crosslinking material having an ethyloxide spacer while heated to 71° C.; coating a reactant mixture comprising a first isocyanate compound and a hydroxyl functionalized fluoro-crosslinking material having an ethyloxide spacer having the general formula of: wherein p and q are integers in a range between 0-50, provided that at least one of p and q are not zero, and x and y are integers between 0-10, onto a substrate, wherein the reactant mixture is coated from a mixture of at least one fluoroalkyl ether solvent and ethyl acetate; subjecting the coated reactant mixture to a first curing treatment at a temperature of about 150° C. for a period of time of about 30 minutes; and thereafter, subjecting the coated reactant mixture to a second curing treatment at a temperature of about 260° C. for a period of time of about 30 minutes.
