MG Chemicals 419D – Acrylic Conformal Coating
- Chemical Family
- Acrylics & Acrylates
Acrylic Conformal Coating 419D is a 1-part acrylic conformal coating that cures to a durable, flexible and smooth finish. 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. 419D creates a robust moisture barrier that protects printed circuit boards in humid environments. It protects effectively against moisture, corrosion, fungus, dirt, dust, thermal shock, short circuits, high voltage arcing, and static discharge.
