How does nano coating work?
In a nutshell, nano coating changes the surface properties of the host material in a way that causes liquids to bead up and either roll off or be removed easily. The following visual shows how water beads up on a nano coated surface more than water on a non-coated surface. Without nano coating – or HPF80 NanoBlock – the water spreads out across the surface.
While earlier nano coating methods were only applied to certain parts of the hearing instruments – usually the outer shells - HPF80 NanoBlock is applied to the entire instrument, both inside and out, for the most complete protection. To illustrate the thoroughness of this protection, we have created a demonstration with compressed sponges. As you will see, the yellow sponge, which is not coated, expands immediately when introduced to water. On the other hand, the blue, HPF80 NanoBlock coated sponge just floats, stays flat and any water simply beads up on the surface.
