This article provides information about sealing PCAP screens

Dust and watertight seals can be achieved with proper integration of PCAP touchscreens. Seals that meet NEMA 4 and 12, and IP65 standards may be accommodated based on integration. When only dirt and dust seals are necessary, open cell foam material can be applied between the touchscreen and bezel. The seal must not contact the active area of the touchscreen. It is important to use non-conductive materials for sealing.

A watertight seal is achievable by applying a gasket around the inactive border region of the cover glass. The gasket must be applied in the inactive border to prevent unwanted touches caused by the gasket pressing on the active area. Elastomer gaskets of almost any type may be used to make a seal between the touchscreen and bezel in this region. 

Open-cell or closed-cell foam gaskets manufactured without sulfur vulcanized elastomers are recommended. Cell foam gaskets manufactured with sulfur can attack the silver electrode pattern of the touchscreen. Recommended elastomers include silicones, polyurethanes, and saturated polyolefins, which are cross-linked using high energy irradiation, peroxide, or other chemical cross-linking reactions.

For specific IP ratings, Elo recommends using a front layer of glass with thickness's up to 6mm and enable the "Touch Through" settings in the monitor's OSD menu. You can then seal the cover glass.
