A nanotechnology-enabled, two-layer coating from NEI Corp. is designed to be a drop-in replacement for trivalent chromium and is formulated to improve the corrosion resistance of zinc-plated and hot-dip galvanized steel.
The coating process consists of applying a self-healing conversion coating (Nanomyte PT-100) followed by a barrier coating (Nanomyte TC-5001). Both coatings are liquid formulations that are amenable to dip coating, brushing and spray coating. The coating technology is designed to protect zinc-plated and galvanized steels surfaces from rusting under severe environmental and operating conditions.
