This is the conformal coating that I've been using to protect my drones for over 4 years. My quads end up in the water nearly every week...and we flew through a bando in the rain yesterday...Wether you end up hitting a droplet of dew on a blade of grass or you sink your quad in the Abyss, Conformal Coating is the way to protect your electronics from water damage.

 

 

MG Chemicals is great for every board on your quad, but dont paint it in buttons, switches, or connectors that you plan to use.

    422C is a 1-part, acrylic-silicone blend waterproof conformal coating that cures to a durable, flexible and smooth finish. It is easy to apply and can be handled in only 10 minutes. It may be removed with appropriate strippers, or soldered through for repair or rework.

    This circuit coating puts minimum stress on components during thermal cycling, making it ideal for applications that involve a wide temperature range. It provides strong protection against moisture, corrosion, fungus, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge.

    This circuit board waterproof coating is the best conformal coating where moisture protection, wide range service temperature, and flexibility are required. It works great as a first-person view (fpv) conformal coating and is an excellent choice for waterproofing remote systems, such as drones and remote-control cars.
