Iranian Company Produces Nanozirconium Coating for More Protection against Rust

“One of the company’s most important achievements over the years has been the development of nanozirconium technology, which is specifically used in sensitive industries that require special protection from rust and environmental damage,” said Farhang Azad, the sales engineering manager of the knowledge-based Schiller Farayand Fars company.

“This technology has been able to replace older coatings like chromium 3 and 6, which were used in various industries, specially in the galvanizing and aluminum industries, due to their environmental problems and risks,” he added.

Azad believes that nanozirconium coatings have significant advantages due to their special structure, saying that these coatings, with their very low thickness compared to traditional coatings, provide greater protection against rust and environmental damage.

“In addition, nanozirconium coatings reduce direct and indirect costs by 25 to 50 percent due to their optimized and economical production process,” he added.

“These coatings are also produced at ambient temperatures without the need for high heating, which reduces energy consumption and production costs,” Azad said.

In a relevant development in 2023, researchers at an Iranian firm had also succeeded in production of nano zirconium conversion coating used in aluminum producing plants and other industries.

“Our company produces nano zirconium coating and aluminum anodizing materials,” said Siamak Ataherian, the managing director of the company.

“Our company is the only producer of nanozirconium conversion coating and has received a certificate of appreciation from the Department of Environment for Green Production,” he added, noting that plants which produce colored sheets, aluminum products and galvanized sheets are among the main customers of his firm.

“Among the main advantages of our company's products, it can be mentioned that they are economical and don't need a lot of energy, they don't have sludge and disturbing deposits, they consume water optimally, and they enjoy a high speed of coating formation reaction, excellent mechanical properties and very simple operation and monitoring,” Ataherian said.

Application of zirconium coating with a very thin thickness (in nanometer dimensions) on steel, aluminum and galvanized surfaces improves parameters like the adhesion of the organic coating and increases the resistance to paint corrosion and cathodic separation of the paint.
