What is the implication of applying the PVD technology in selected BISK fittings?

PVD is an innovative and sophisticated technology which proved superior to that of the galvanisation of surface of various accessories. Using the physical phenomena (crystallisation of gas particles in vacuum) allows to make a thin but hard and very strong layers, which make an even surface, well bound with the base. Applying hard PVD layers increases the life expectancy of the surface and its resistance to damage (effacing, scrunching, breaking) and to wearing.
