PERMABOND UV681 is a cure-configurable coating. Since it's curable to UV light it makes for a very configurable and customizable curing coating.
It is ideal for coating small parts and electronics (such as conformal coating) to protect against environmental and vibrational damage. The optically clear / tack free formulation also makes this product particularly suitable for coating smart card microchips amongst various other applications. Its low viscosity ensures an even, bubble-free coating and high temperature resistance allows it to resist wave-soldering.
