The hot zone compromise

Nacelles and Exhaust Zones Exceed Polyurethane Limits.

"Nacelles, thrust reversers, and APU compartments routinely exceed 177°C / 350°F — beyond polyurethane limits. Current solutions force trade-offs between thermal protection, chemical resistance, and flexibility."

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

Polyurethane
Fails above 177°C / 350°F

Catastrophic failure at hypersonic surface temperatures

Ceramic
Prohibitive weight and rigidity

Cracks under thermal shock, kills payload margin

Bare Metal
Oxidation and signature risk

Corrosion compromises radar cross-section over mission life

Silicone
Brittle at extreme temperature

Delamination under vibration and thermal cycling

Why materials engineers choose GREOS

Reduce Repaint Cycles While Cutting Component Weight.

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.

Hypersonic Thermal Protection
GREOS APEX FFKM maintains elastomeric properties at 350°C / 660°F longterm — protecting leading edges where aerodynamic heating destroys conventional coatings.
Directed-Energy Weapon Housings
High-power laser and electromagnetic systems generate extreme localized heating. GREOS coatings protect weapon housings without thermal degradation or outgassing.
Signature Management
Maintains smooth, uniform finish critical for radar cross-section control. Chemical inertness prevents surface degradation that compromises low-observable properties.
Design Freedom for Advanced Airframes
Eliminates thermal design constraints. Thin-film application preserves vehicle lines and weight budgets without compromising protection.
MIL-SPEC Fluid Resistance
Proven resistance to fuels, hydraulic fluids, and de-icing agents across the full operating temperature range.
Depot-Compatible Application
Standard spray application. No special equipment. Compliant for defense manufacturing and depot operations.
