USA Nanocoat’s CircuitDry™ is an easy-to-apply liquid coating solution ideal for protecting electronics from moisture and corrosion. The PFOS/PFOA-free fluoropolymer liquid chemistry relies on a proprietary C6 fluorocarbon to provide hydrophobic and oleophobic properties to electronic substrates. Industries, where CircuitDry™ is currently being used, include consumer electronics, avionics, aerospace, unmanned systems, and military. Adheres well to a wide variety of material substrates including plastic, glass, metal, and ceramic.
The solution is easily applied by dip, spray, spin, flow, or syringe coat, and suspended in a non-toxic, non-flammable, hydrofluoroether solvent that is compatible with a variety of materials. Minimal to no masking is required depending on assembly configuration. CircuitDry™ dries in seconds to a thin, transparent film with excellent anti-wetting properties against liquids including water, oil, and a variety of chemicals such as heptane, toluene, and acetone. CircuitDry™ is an excellent product for electronic manufacturers, assemblers, and contract coating facilities to provide an effective solution at a lower cost.
Just realized you forgot to take your brand new phone out of those jeans you washed? Instead of running to the store for some dry, uncooked rice to soak up the moisture, you remember you’re covered. You protected your new investment with the latest nanocoating technology called CircuitDry™. CircuitDry™ is a hydrophobic fluorocarbon-based liquid that has been in use by the consumer electronics, avionics, aerospace, unmanned systems, and military industries for the past decade. Now, you and your electronics can be protected by this same cutting-edge technology.

Does Not Alter Appearance
The coating can be used continuously at temperatures of 150°C and for about an hour at 250°C. The coating begins to decompose between 250°C -300°C.
The film is flexible and this property does not change over time.
Yes, it is added to the ready-to-use solution and will remain visible in the film.
Excitation: 373 nm; Emission: 460nm
The coating is breathable, and therefore gas permeable.
A soldering tip usually is between 600 and 800°C, which causes the film to transition to the gas phase and evaporate.
No, the coating is too thin.
The IPX scale rates water ingression into a device. Our coating can help your device achieve a level of IPX by preventing your phone from water damage. Our coating does not prevent water ingress into a device like a traditional case with mechanical seals, but instead prevents the electronics from failing when exposed to water.
Fluids, greases, creams, waxes, paints, glues, flux, etc. will dissolve due to the solvent, but will not affect the polymer as it is inert. These materials can be filtered and remove from the coating solution. It is recommended to perform a solids concentration analysis after filtering. It is recommended to avoid strong bases.
