Gerdau Graphene (Sao Paulo, Brazil), a nanotechnology company pioneering advanced graphene-enhanced materials for industrial applications, recently announced the availability of NanoCORR Shield as the newest product from its G2D NanoCORR line of anti-corrosion paints and coatings additives. 

Developed with Gerdau’s exclusive G2D technology, NanoCORR Shield is a graphene-enhanced chemical additive designed to increase the corrosion resistance of solvent-based paints and coatings. According to the company, NanoCORR Shield has demonstrated a 30-70% increase in corrosion resistance when subjected to salt-spray testing.

“G2D NanoCORR Shield was designed to help producers deliver ultra-high-performance paint and coating products while reducing the use of non-sustainable inputs such as heavy metals,” says Valdirene Peressinotto, executive and innovation director. “This product joins our expanding portfolio of additives serving the paints and coatings market and underscores our commitment to developing innovative, sustainable graphene-based solutions for this industry.”

The addition of a small amount of specially-developed graphene—an ultra-strong carbon nanomaterial—into paints and coatings allows for an increase in the barrier effect against corrosive elements such as water, oxygen, and chlorides, according to Gerdau. 

In addition, NanoCORR reduces paint consumption by reducing the nominal thickness of the coating while maintaining other characteristics and performance properties, the company explains.

NanoCORR complements Gerdau’s growing line of chemical additives for the paints and coatings market, which includes the G2D NanoCORR anti-corrosion additive for water-based paints and coatings; G2D NanoLAV W107, which improves the washability of latex-based paints; and G2D NanoDUR W102, which increases the durability of latex floor paints. 

In recent testing, NanoDUR W102 demonstrated a 33% reduction in paint consumption and application, thereby reducing the frequency of repainting by up to a third, the company explains.

“NanoCORR offers a quality solution to combat corrosion and extend the useful life of metal structures, reducing the need for frequent maintenance and associated costs,” says Alessandra Zanuto, technical manager of products and sales of chemical additives. “Its positive impact goes beyond protection against corrosion, promoting sustainability and economic efficiency in multiple sectors.”
