HZO is an ITAR certified provider of ultra-thin conformal coating solutions for the protection of mission-critical electronics and PCB assemblies within UAVs (unmanned aerial vehicles) and robotics.
Our robust coatings are ideal for drone OEMs and systems integrators looking to enhance the reliability and longevity of their products even under the harshest of environments, and are suitable for mass manufacturing applications. We offer a variety of options, including conformal coatings that meet ASTM and military standards.
We offer complete turnkey solutions that ensure foolproof protection for your electronics, and are uniquely customized for your manufacturing and budget requirements. Our proven processes integrate expert knowledge with advanced materials science and state-of-the-art equipment, and we have the capacity to undertake production runs of any size, allowing you to scale up to quantities of up to millions of units.
Lightweight, ultra-thin conformal coatings for drones & robotics
Our thin-film coatings provide a lightweight alternative to bulkier traditional methods such as potting, with almost no added weight to the assembly. The result is highly reliable electronic systems with no impact upon SWaP (size, weight and power) budgets, payload capacities or flight times.
