HZO stands as an ITAR-certified leader in providing ultra-thin conformal coating solutions designed to safeguard mission-critical electronics and PCB assemblies in UAVs (unmanned aerial vehicles) and robotics.
Our advanced coatings are perfectly suited for drone manufacturers and systems integrators aiming to boost the durability and reliability of their products, even in the most extreme conditions. They are also tailored for high-volume manufacturing needs.We present a diverse range of options, including conformal coatings that comply with ASTM and military specifications.
We provide comprehensive turnkey solutions that guarantee reliable protection for your electronics, customized to meet your manufacturing and budgetary needs. Our established processes combine expert knowledge with cutting-edge materials science and advanced equipment, enabling us to handle production runs of any scale, accommodating quantities of up to millions of units.
Lightweight, Ultra-Thin Coatings for Drones and Robotics
Our thin-film coatings offer a lightweight choice to traditional bulkier methods like potting, adding negligible weight to the assembly. This results in highly dependable electronic systems without affecting SWaP (size, weight, and power) parameters, payload capacities, or flight durations.

- Rain and snow
- Dust
- Salt spray
- Humidity
- Pollutants and chemicals
- Extreme temperatures
HZO’s durable hydrophobic coatings provide superior resilience in even the most demanding conditions faced by industrial, aerospace, and military-grade systems, ensuring your UAVs and autonomous vehicles continue to function when failure is not an option.
