COMPARISON BETWEEB A NORMAL DIPPING VARNISH AND HIGH COAT
Scale of rising hardness values:
2B (-2), B (-1), HB (0), H (1), 2H (2), 3 H (3), 4H (4), 5H (5), ...
The parts varnished with dipping varnish begin to corrode after 20 hours of being sprayed with a salt spray mist, while the articles treated with the HIGH COAT process show no signs of corrosion in the salt spray mist, even after 1500 hours.
