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 well as a first-person view (fpv) conformal coating and is an excellent choice for waterproofing remote systems, such as drones and remote-control cars.
This product is also available in spray and pen formats.

We also offer epoxy (4225), polyurethane (4223F), and UV-curable (4200UV) conformal coatings.
