NEI Introduces Self-healing Anti-corrosion Coating for Zinc-Plated and Galvanized Steel

NEI Corporation recently introduced NANOMYTE® TC-5001, a nanotechnology-enabled, single component, clear coating that significantly improves the corrosion resistance of zinc-plated and hot-dip galvanized (HDG) steel. It is amenable to dipping, brushing, and spray coating. The new coating technology is designed to protect zinc-plated and galvanized steel surfaces from rusting under severe environmental and operating conditions. Applications of the coating technology include protecting outdoor structures (e.g., electrical grid structures, street lights, and lattice beams), hardware (e.g., rods, pipes, nuts, bolts and screws), automotive components and farming equipment. 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. The NANOMYTE® line of coatings provides an array of advanced protective surface treatments for metal, wood, and polymers. The coatings have tailored functionalities such as anti-corrosion, self-healing, scratch resistance, anti-ice, and easy-to-clean. In addition, NANOMYTE coatings are versatile and can be modified to introduce color and other features to meet performance and aesthetic requirements.
