PERMABOND UV681 has been developed for use as a coating. It is ideal for coating 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.
