4223D - Premium Polyurethane Conformal Coating




4223D is a one-part, heat curing, thermoset polyurethane conformal coating that cures to a durable, flexible, scratch resistant and smooth finish. It is easy to apply and can be handled in as little as 15 minutes. It cures in only 2 hours at 100 °C (212 °F). It may be removed with appropriate strippers, or soldered through for repair or rework.

4223D protects printed circuit boards in chemically challenging environments. It provides strong protection against aggressive chemicals, corrosion, moisture, fungus, dirt, dust, thermal shock, abrasion, short circuit, high-voltage arcing, and static discharge.
