ZnCOAT® Black
8-10 µm
Corrosion protection
It passes IFI-170 (16 cycles, Duration B) and QUV (>1000 hours with no change in appearance) cyclic tests. It also ensures bimetallic compatibility with aluminum alloys.
Friction control
- * Results depend on substrate, geometry of parts and type of application processes.
- ** Can be waxed to modify friction.
Improved corrosion resistance to fertilizer.
Implemented via non-electrolytic application processes. This avoids the hydrogen embrittlement phenomenon that causes cracking of metals.
Processes
ZnCOAT® Black is applied via bulk dip/spin, rack dip/spin, spray or electrostatic spray. This variety of processes allows to coat all types of parts, even those requiring partial coating, or with recessed and hollow surfaces.
Moreover, they are non-electrolytic and thus avoid the phenomenon of hydrogen embrittlement which causes cracking of metals.
Solventborne zinc flake
ZnCOAT® Black is a solventborne zinc flake coating designed as an alternative to zinc plating. Compared to conventional zinc plating, which is passivated using hexavalent or trivalent chromates that provide a thin-film passivation layer only on the surface, ZnCOAT® Black is chrome-free and contains passivating agents and corrosion inhibitors throughout the film.
