In some embodiments, a primer and/or an epoxy can also be used. Uses of material sputtering or sputtered materials are also provided to bond a parylene substrate and silicone elastomer, or to enhance the relative strength of the bonding between the two. In addition, composite materials, and the use thereof, involving a parylene substrate, an elastomer receptacle, and liquid silicone are provided.

Devices and methods covering a gap between an edge of a surface and a body exposed through an opening in the surface defined by the edge. Such a device has at least first and second sections formed of different materials. The device is positioned so that the second section is over a portion of the surface adjacent the opening and the first section extends over the gap and the opening. After removing a release liner releasably secured to a backside of the first section to cover an adhesive, portions of the first section are bent and molded to plastically conform the portions to the edge of the surface while the second section remains over the portion of the surface adjacent the opening. The body is then contacted with the backside of the first section such that the backside of the first section is adhered to the body with the adhesive.
