Currently, the preferred abrasion-resistant camouflage
coatings are filled polyurethane paints. These paints
have moderate high-temperature resistance, but very poor
long-term wear resistance at high temperatures and they
degrade over time, resulting in the need for frequent
repair and recoating. However, the Air Force needs
abrasion-resistant coatings that can withstand high
temperatures for longer durations and that match the
existing camouflage paint schemes of aircraft parts. TRI
evaluated a variety of raw materials, developed numerous
coating formulations in conjunction with the
experimental design development process and then
identified the best formulations.
The new Proteckt camouflage coating offers greatly
improved high-temperature abrasion resistance for
aerospace composite applications. The coating cures
faster, is resistant to standard aircraft fluids, meets
color and gloss requirements, and exhibits good
adhesion, even after accelerated fluid exposures.
can be applied using traditional procedures, including
brush, roller and high-volume low-pressure spray. Due to
high interest in the product, the firm received a $1.3
million Rapid Innovation Funding award to further
advance the technology.
