4223F - Urethane Conformal Coating

4223F is a 1-part, heat curing, UL 746E and IPC-CC-830B certified, thermoset urethane (UR) conformal coating. It cures to a durable, flexible, scratch resistant and smooth finish. It is easy to apply and can be handled in 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.

This PCB resin coating is considered to be one of the best conformal coatings for protecting 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.
