419C - Fast Drying Acrylic Conformal Coating




419C is a fast drying acrylic conformal coating that cures to a durable, flexible and smooth finish. This 1-part coating is easy to apply and can be handled in only 5 minutes. It is a great option for speeding up board production throughput without additional capital investment.

This acrylic conformal coating has a high dielectric strength and can be readily removed with appropriate strippers, or soldered through for repair or rework. 419C creates a robust moisture barrier that protects printed circuit boards in humid environments. It strongly protects against moisture, corrosion, fungus, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge.
