Corn
Hybrid Polymer Coating Removal on Delicate Substrates
Project Number: 06-CR-031
JG-PP
is assisting in coordinating the evaluation of using corn based blasting
media as a potential process to remove coatings from radomes and other
delicate substrates during maintenance, repair and overhaul operations.
By consolidating the two Navy and one Army projects into one JG-PP
project, JG-PP
is able to leverage valuable resources and ensure no duplication of effort
in evaluating corn based blasting media. Furthermore, through this coordinated
effort, JG-PP
can assist in transitioning a cost effective, environmental friendly technical
solution for DoD
and NASA.
Coating removal and selective stripping processes are performed during
maintenance, repair and overhaul activities. Navy and Air Force aeronautical
radome repair operations currently use solvents (e.g., toluene, xylene,
and MEK)
that have been targeted for minimization or elimination to remove the
coatings. The purpose of this consolidated JG-PP
project is to demonstrate and validate the effectiveness of Corn Hybrid
Polymer (CHP) blasting technology. CHP is an isolated polycrystalline
byproduct material resulting from the commercial processing of corn. It
offers an effective alternative to solvent treatment as a means to remove
coatings from various composite substrates. An evaluation was conducted
on U.S. Navy surface ship radome sections, indicating that this media
provides acceptable stripping rate without damage to the surface. This
project is targeting NAVAIR
and Air Force aeronautical radomes that undergo coating removal evaluation
during require routine maintenance and repair service. Other DoD
and NASA
delicate substrates components will also be evaluated as part of this
effort. Several JTPs
are planned for development in this effort. A Project Team has been assembled
with representatives from the NDCEE,
NAVAIR,
Naval Surface Warfare Center, Carderock Division, NASA
Acquisition Pollution Prevention Office, and a JG-PP
representative.
