Looking for better, more consistent performance?
Due to toxicity issues, regulations have been issued that limit or even ban the use of certain materials, including hexavalent chromium (Cr+6) which has been used extensively as passivation for zinc plating. Many Cr+6 applications have been replaced by trivalent chromium (Cr+3). Unfortunately, Cr+3 performance has been inconsistent and poor when compared to Cr+6. Other surface treatments can provide higher performance and more consistent quality, but they are more costly, and often offer more performance than the application requires.
ZnCoat® offers superior corrosion resistance and consistent quality for no extra cost when compared to commercial zinc/trivalent, baked for hydrogen embrittlement relief. ZnCoat® is chrome-free, does not promote hydrogen embrittlement and is a thin coating (8-10μm / 0.3-0.4 mils) that is an ideal drop-in replacement for applications that currently call for environmentally compliant zinc plating.
