COVEN FP3106 is an ideal alternative conformal coating for 3M Novec 1908, which is designed for the protection of printed circuit boards and electronic components. It is a low-viscosity solution of an 8 wt% fluorochemical acrylic polymer carried in a hydrofluoroether solvent. It is UV detectable.
COVEN FP3106 is also designed for moisture and corrosion protection of printed circuit boards and electronic components.
