The problem

Why Traditional Coatings Fall Short

Modern aircraft demand more from their surface protection. High-speed flight, advanced engines, and electric propulsion create thermal challenges that conventional coatings were never engineered to solve. Every existing solution forces a trade-off between heat resistance, weight, flexibility, and finish quality.

Forced compromises.
For decades.

Until now.

≤ 177°C / 350°F
Polyurethane Topcoats
  • Thermal degradation above 177°C
  • Poor chemical resistance
  • Frequent repaint cycles
  • Not suitable for next-gen platforms
≤ 315°C / 600°F
Silicone Coatings
  • Rigid — prone to cracking
  • Poor fuel & solvent resistance
  • No vibration flexibility
  • Difficult aesthetic finish
538°C+ / 1000°F+
Ceramic Barriers
  • Heavy — significant weight penalty
  • Zero vibration tolerance
  • Unaesthetic appearance
  • Complex application process
Material Dependent
Bare Metal / Shields
  • Heavy weight penalty
  • Corrosion & oxidation prone
  • No fluid protection
  • Visually inconsistent

The GREOS solution

No Compromise. No Exceptions.

The first elastomeric coating system that delivers extreme temperature resistance without sacrificing flexibility, weight, chemical resistance, or finish quality.
