ELPEGUARD® conformal coatings​

ELPEGUARD® conformal coatings are used to protect and insulate assembled pcbs so that they can fulfil higher requirements regarding reliability and service life.

Solvent-containing or aqueous 1- and 2-pack ready-to use systems with very good resistance against moisture and condensation, thus enabling an excellent corrosion protection for assembled pcbs (e.g. e-corrosion and migration), typical dry layer thickness < 80 µm, suitable for coating flexible circuits (“flex-to-install”); can be soldered through for repair or removed mechanically (blasting method); coloured-transparent, opaque or fluorescent adjustments permit a simple checking of the coating layer for completeness by daylight or UV light (black light)
