Use Case: Space & Launch Systems

Elastomeric Coatings Engineered for the Extremes of Space.

Replace brittle silicones and heavy heat shields with flexible, fuel-resistant coatings for nacelles, thrust reversers, and engine bays.

700°C+
Thermal range (cryo to plume)
FFKM Chemistry
Near-PTFE inertness
LEO Ready
Atomic oxygen resistant

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
Shatters at cryogenic temperatures

Catastrophic delamination during cryogenic fueling operations

Silicone
Brittle below −100°F

Thermal shock failure at launch, poor atomic oxygen resistance

Ceramic
Weight penalty kills payload capacity

Rigid, heavy, complex application — incompatible with deployables

PTFE Coatings
Poor mechanical strength

Adhesion failure, surface prep complexity, limited formability

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.

Flexible from −40°C to 350°C / 660°F
FFKM maintains elastomeric properties across a 700°C+ temperature range. While competitors crack during cryogenic fueling, GREOS coatings flex, adhere, and protect through every cycle.
Atomic Oxygen Resistance
In low Earth orbit, atomic oxygen erodes organic materials at 3mm per year. Fluoropolymer chemistry provides molecular-level resistance — your coating stays intact while everything else disintegrates.
Propellant-Compatible Chemistry
Compatible with LOX, LH2, hypergolics, and every propellant chemistry in use today. PTFE-level chemical inertness in a sprayable system.
Mission-Critical Weight Savings
Every pound to orbit costs thousands. Thin-film protection under 0.5mm replaces heavy thermal barriers without sacrificing performance.
UV and Radiation Resistance
Sustained UV and radiation exposure in LEO and GEO. FFKM chemistry maintains coating integrity without chalking, cracking, or outgassing that compromises mission performance.
Cryogenic Thermal Cycling
Withstands 200+ thermal cycles per day from cryogenic fueling through launch plume exposure — without delamination or loss of adhesion.
