Low Surface Energy Fluoro-Epoxy Coating for Drop-On-Demand Nozzles

A low surface energy coating is needed for an ink jet print head, and this coating comprises a fluoro-epoxy.

It has been known to produce a low surface energy coating on an ink jet head to prevent wetting of the nozzle face, and TEFLON* is one material that has been suggested for use. However, TEFLON material has poor adhesion characteristics on some surfaces.

A fluoro-epoxy coating has been found to produce a satisfactory low surface energy coating which is resistant to wear, is non-soluble in ink, and does not readily absorb water. In addition, the wetting angle was found to be very similar to that measured for TEFLON material. The specific fluoro-epoxy material found to be suitable is
