A study was conducted to develop and validate a Pressurized Water Stripping (PWS) process for use on aircraft and aircraft components to allow selective removal of the topcoat. By design, the process incorporates a barrier coating to encapsulate either the epoxy (MIL-P-23377) or polyurethane (TT-P-2760) primer used on military aircraft today. Then a water-only stripping process is used to remove the MIL-C-85285 polyurethane topcoat leaving the primer and barrier coatings intact. This system includes an inexpensive method for removing and reapplying the topcoat without disturbing the underlying primer or substrate. The barrier coating is designed to be resistant to moisture and erosion damage by the Pressurized Water Stripping process.
