419D-340G – Acrylic Conformal Coating Spray

419D-340G is a fast-drying acrylic conformal coating spray that cures to a durable, flexible and smooth finish. It is easy to apply and can be handled in 10 minutes. It can be readily removed with the right stripper or soldered through for repair or rework.

Packaged in a convenient aerosol can, this conformal spray creates a robust moisture barrier that protects printed circuit boards in humid environments. It strongly protects against moisture, corrosion, condensation, fungus, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge.

This product is also available in liquid and pen formats.
