Features
Made to Order, 1 Pail per Order
Our 4223F Polyurethane Conformal Coating is a heat curing, one part product that provides an excellent scratch, chemical resistant finish, meets UL 94-V0, and free of xylene and other hazardous air pollutants. This one part coating is easy to use and repair: it does not require special or costly equipment or materials. It is ideal for chemically challenging environments.
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.
