| description | Disclosed herein are methods for reducing drooling, wetting or adhesion on a front face of an ink jet printhead configured for ejecting aqueous ink. The methods including disposing an anti-wetting, low adhesion coating onto a surface of the ink jet printhead front face, wherein the anti-wetting, low adhesion coating is a reaction product of a reactant mixture comprising a triisocyanante and a perfluoropolyether diol compound comprising an ethyoxylated spacer; and ejecting a drop of an aqueous ink comprising a surfactant from the printhead, wherein the aqueous ink drop exhibits a contact angle of greater than about 40° and a sliding angle of less than about 30° with a surface of the coating on the ink jet printhead front face. |
