4225 - Epoxy Conformal Coating

4225 is a 2-part epoxy protective coating that conforms to a durable, tough, semi-flexible coating with an excellent finish. It protects against harsh chemicals, humidity, corrosion, oil, dirt, thermal shock, and abrasion. It also prevents high-voltage arcing, short circuits, and static discharges.

This circuit board epoxy coating is a promising choice where extreme physical and chemical resistance are required.

For a UL 746E-certified acrylic conformal coating, visit 419E.

We also offer polyurethane (4223F), and UV-curable (4200UV) conformal coatings.
