Use Case: Advanced Air Mobility (eVTOL)
Replace brittle silicones and heavy heat shields with flexible, fuel-resistant coatings for nacelles, thrust reversers, and engine bays.
The hot zone compromise
Every coating on the market solves one problem and creates three more. Silicones handle the heat but crack under vibration and don't resist Skydrol. Ceramics are too heavy. Polyurethanes fail at temperature. Bare metal corrodes and adds weight. Engineers have been living with these compromises for decades.
GREOS ENDURE eliminates all four failure modes simultaneously — in a standard spray application that drops into existing finishing workflows.
Why current solutions fall short
Fails at motor housing temperatures, no dielectric protection
Conventional topcoats offer no protection for HV systems
Heavy ceramic systems unacceptable for weight-critical eVTOL platforms
Delamination under vibration, no electrical insulation properties
Why materials engineers choose GREOS
GREOS ENDURE is the only coating 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.
Where to specify GREOS
GREOS ENDURE is designed for any airframe surface where thermal demand exceeds polyurethane limits while maintaining flexibility, chemical resistance, and OEM finish requirements.
Environmental compliance
GREOS coatings use California CARB-exempt solvents and non-PFAS dispersants, meeting stringent environmental regulations without compromising performance. Compliant for OEM manufacturing and MRO depot operations in California and global markets.
Testing & qualification
GREOS ENDURE formulations are designed to meet recognized aerospace and aviation standards. 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.
