422B-340G 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 8 minutes. It may be removed with the right conformal coating remover (MG’s 8309 or 8310A) or soldered through for repair or rework.

This silicone coating spray is designed for applications where both high service temperature and flexibility are required. It 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 product is also available in liquid format. For acrylic conformal coating sprays, see 419D-340G or 419E-340G, and for urethane conformal coating sprays see 4223F-312G.
