HZO is a leading provider of conformal coating solutions for the protection of mission-critical electronics and PCB assemblies within UAVs (unmanned aerial vehicles) and robotics. UST is delighted to welcome HZO on board as a supplier partner, and we will be highlighting their unique solutions and capabilities across our channels over the next 12 months.

We’ve just launched HZO’s UST supplier profile, which has been written and built by our team in collaboration with the company. The Silver profile showcases their robust hydrophobic coatings, which 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.

protective coatings for dronesHZO’s 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.

The conformal coatings protect sensitive drone and robotic systems electronics from a wide range of environmental stressors that can cause shorts, corrosion, and other faults. These factors include rain and snow, dust, chemicals, extremes of temperature and more. HZO offers a variety of lightweight and ultra-thin protective coatings to suit a wide range of operational requirements.

Guardian parylene coatingsGuardian parylene coatings are applied using a chemical vapor deposition (CVD) process, resulting in a highly uniform, pinhole-free and ultra-thin protective barrier that penetrates every space and wraps around every edge. These films typically range from around 2 to 25 microns in thickness, achieving robust protection against water damage, corrosion and electrical failure in a fraction of the amounts required by conventional coatings.

Parylene offers a variety of highly desirable properties, including excellent dielectric performance, good abrasion resistance, superior chemical resistance, and low thermal expansion. It also features very low levels of outgassing, making it ideal for satellite and space applications.

Sentinel plasma-applied nanocoatingsSentinel plasma-applied nanocoatings provide protection at the molecular level, and are ideal for coating printed circuit board assemblies (PCBAs) as well as individual connectors and semiconductors.

These cost-effective hydrophobic coatings protect against a wide variety of liquids and gases while ensuring that your electronics stick to weight limits and precision thicknesses.

ALD ultra-thin coatingsHZO’s Defender coatings provide pinhole-free protective coverage at the nanometer scale, with unparalleled precision control over the film thickness. They are ideal for complex 3D structures and geometries and difficult-to-protect surfaces that can be highly challenging to coat uniformly with other technologies.

Defender ALD (atomic later deposition) coatings include nontoxic materials and deliver ultra-low moisture and gas permeability even up to very high temperatures, as well as robust protection against radiation, outgassing and oxidation.
