419E-340G is an acrylic-based circuit board coating spray that is designed to enhance circuit boards’ environmental protection. This circuit board coating spray is one of the few coatings on the market that is certified to both UL 746E and IPC CC 830 standards. It is easy to apply, can be handled in 15 minutes, and cures to a durable, flexible, and smooth finish. It can be readily removed with the right strippers, or soldered through for repair or rework.

This protective coating spray creates a robust barrier for humid and aqueous environments. It also strongly protects against corrosion, fungus, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge.

This product is also available in liquid format. For urethane coating spray, see 4223F-312G; for silicone coating sprays see 422B-340G or 422C-340G.
