The 419D-P White Overcoat Pen applies an acrylic coating that cures to a durable, 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. This pen can be used to repair scratches and chips in permanent solder masks, 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.
