NEI Corp., Somerset, N.J. introduces Nanomyte TC‐5001, a nanotechnology-enabled, single component, clear coating that significantly improves the corrosion resistance of zinc‐plated and hot‐dip galvanized steel under severe environmental and operating conditions. The photo shows galvanized bolts that were subjected to salt spray testing. The TC-5001-coated bolt on the left shows no corrosion after 168 hours, whereas the bolts on the right show extensive rust.
It is amenable to dipping, brushing, and spray coating. The dense barrier coating can be used as a standalone coating, as well as in combination with Nanomyte PT‐100, a self‐healing conversion coating. In salt‐spray tests (SST, ASTM B117), uncoated zinc‐plated steel bolts exhibited white rust in 24 hours and red rust after 168 hours. In contrast, the Nanomyte coating provided significant corrosion protection, even after 504 hours of SST.
Typically, TC-5001-coated parts show no white rust even after 1000 hours, and no red rust even after 1200 hours. SST can be used in conjunction with field testing and online life predictors for coatings on HDG, as prescribed by the American Galvanizers Association (AGA).
