No competitor can match this. GREOS ENDURE delivers longterm thermal protection, true elastomeric flexibility, and exceptional resistance to flight line fluids — all in a standard spray application (or roll) with no process changes required.
What no one else can do
For decades, aerospace engineers have been forced to choose: thermal protection OR flexibility OR chemical resistance. The competition delivers one, maybe two. Never all three.
GREOS ENDURE is the only solution that delivers 250°C / 480°F thermal protection with true elastomeric flexibility AND flight line fluids resistance. This capability does not exist anywhere else in the aerospace coatings industry.
GREOS ENDURE delivers all of this — simultaneously
Longterm thermal exposure. Proven in hot zone environments.
True flexibility under vibration. High elongation maintained.
Excellent vs fuels, hydraulic fluids, de-icing agents, and solvents.
Applies with existing equipment. No process changes required.
Thin-film application. Measurable weight savings vs heat shields.
CICP pigments with aerospace flight heritage. Consistent finish.
The forced compromise
Every coating on the market fails at least one critical requirement. Most fail three or four. This is why hot zone protection has been a compromise for decades — until GREOS ENDURE.
The GREOS ENDURE advantage
GREOS ENDURE is the only aerospace coating that delivers on every critical requirement simultaneously — thermal performance, flexibility, chemical resistance, weight, and aesthetic quality.

The chemistry behind it
FKM fluoroelastomer chemistry has powered high-performance seals for decades. The carbon-fluorine bonds deliver unmatched thermal stability and chemical resistance.
But no one has made it sprayable for aerospace. Until now. GREOS ENDURE formulates FKM as a high-performance topcoat that applies with standard spray equipment using CARB-exempt solvents — dropping breakthrough performance into existing finishing workflows.
No special equipment. No process changes. Just performance that no competitor can match.
Primary applications
GREOS ENDURE is designed for commercial and military aircraft hot zones — any surface that demands thermal protection without sacrificing weight, flexibility, or finish quality.
GREOS ENDURE integrates into existing OEM and MRO finishing workflows with standard spray equipment and CARB-compliant solvents — no qualification of new application processes required.
Testing & validation
GREOS ENDURE formulations are designed to meet recognized aerospace standards, ensuring qualification-ready performance in demanding flight environments. GREOS provides evaluation samples and test method reference suites for customer qualification programs.
Performance characteristics and temperature ratings are based on internal laboratory testing. Actual results may vary by application, substrate, and operating conditions. Customers should conduct their own testing to confirm suitability for specific use cases. Information provided is for reference only and does not constitute a warranty or performance guarantee.
