ABchimie746 E UV  is a soft, permanent and transparent new conformal coating. It cures under UV light and it is designed to protect PCBAs from harsh environments. ABchimie746 E UV  benefits from dual-cure technology (UV/humidity) which allows reticulation in shaded areas.

ABchimie746E UV LED may be applied by brush, pad printing, spray machine and of course selective coating machine which is the ideal way to apply. The low viscosity of our system permits to limit the thickness around 80 microns. ABchimie746E UV LED is compliance with REACH and RoHS regulations.
