Development of high-performance Cr-free coating

“Chromium-free” is CSC’s commitment to environment protection. Since 2003, Cr-free environment-friendly coatings had been phased into our galvanized (GI) and electrogalvanized (EG) coils as anti-finger-printing and passivation products. And we are keeping on promoting the performance of coatings by researching and developing advanced Cr-free technologies to exceed our customers' needs.

In 2006, CSC leaded the industry to realize electromagnetic steel (ES) products with C6N8-2 Cr-free insulating coatings. Through the development and optimization in organic binder and inorganic matrix, the second generation of our Cr-free ES coating (C6N8-2) that has lower volatile organic content (VOC) and excelled coating performance (interlayer resistance, adhesion to substrate, anti-corrosion capability…etc) was presented in 2013. The Cr-free C6N8-2 coating can perform exceedingly well not only for general-purpose products, but can also fulfill the critical requirements for high-performance applications (wind generators, electric and hybrid vehicles, high-efficiency motors…etc).
