Circuit Board Waterproofing Spray 422C-445ML MG Chemicals

422C-445ML MG Chemicals is a 1-part, acrylic-silicone blend conformal coating spray that cures to a durable, flexible and smooth finish. It is easy to apply and can be handled in just 10 minutes. It may be removed with the right conformal coating remover (MG Chemicals 8309 or 8310A) or soldered through for repair or rework.

This circuit board waterproofing spray 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 waterproofing spray is the best coating spray where PCB moisture protection, a wide range of service temperatures, and flexibility are required. It is an excellent choice for waterproofing FPV (first-person view) electronics and remote systems, such as drones and remote-control cars.

This product is also available in liquid format.

For acrylic conformal coating sprays, see MG Chemicals 419D-340G or 419E-340G, and for urethane conformal coating sprays see MG Chemicals 4223F-312G.
