The 422B-P pen applies an acrylic-silicone blend conformal coating that cures to a highly flexible and smooth finish. It functions as both a solder resist and a conformal coating. It is easy to apply and can be handled in 10 minutes. It may be removed with appropriate strippers, or soldered through for repair or rework.

422B-P is used to touch up areas missed during conformal coating applications, or to repair conformal coatings after replacing isolated components. It can also be used to protect conductive pen traces.
