Jettable fluid delivery and other MEM devices are being exposed to more extreme environments. These packages rely on polymeric materials as structural adhesives for various substrates. These polymer materials also provide protection from mechanical shock; extreme thermal cycles, and can withstand long exposure to harsh chemical environments of the jetting fluids. This paper will compare performance of acrylate, epoxy and silicone adhesives with exposure to the harsh environments of solvent, aqueous, UV and hot melt inks. Physical properties of the adhesives will be monitored before and after exposure to the inks.
