ZS 8151 has been manufactured particularly for the automtive industry to meet the specifications set for zinc coatings . ZS 8151 is a product developed to protect chromated zinc plated articles against to corrosion in extremely difficult conditions (in and out of the engine ).

300 hours white and 750 red rusts has not been observed after 1 hour at 120°C thermal shock when ZS 8151 is applied on 10 microns zinc plated articles.

Inert protective films on the chromate layer is never completely water and air proof for the industrial products. Indeed, 2 or 3 microns coated lacquer, varnish or polymers , especially after the thermal shock has never fully waterproof.
