419D - Acrylic Conformal Coating

419D is a fast drying, acrylic based circuit board protective coating that cures to a durable, flexible and smooth finish. This 1-part circuit board coating is easy to apply and can be handled in 10 minutes. It can be readily removed with appropriate strippers, or soldered through for repair or rework.

This circuit board coating creates a robust moisture barrier that protects printed circuit boards in humid environments. It strongly protects against moisture, condensation, humidity, corrosion, fungus, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge.

This product is also available in spray and pen formats.
