Abstract:
An ink jet printer nozzle plate of the type containing nozzle holes and having a durable non-wettable layer on at least one surface thereof, said surface being positionable adjacent a media to be printed, the nozzle plate comprising a polyimide material and the non-wettable layer consisting essentially of a derivative of an amine-terminated silane compound, the amine-terminated silane compound derivative being covalently bound to the polyimide material of the nozzle plate and a derivative of a halogen-free polydialkylsiloxane compound having a number average molecular weight ranging from about 400 to about 150,000 and an end group reactive with the amine-terminated silane compound derivative, the polydialkylsiloxane compound derivative being bound to the amine-terminated silane compound derivative by a condensation reaction to provide the durable non-wettable layer on the surface of the nozzle plate.
