A Graphene-Enhanced Anti-Corrosion Chemical Additive
G2D NanoCORR product improves anti-corrosion performance with lower chemical dosage and makes paint production more sustainable.
Gerdau Graphene, the nanotechnology company creating graphene-enhanced materials for industrial applications, announcd NanoCORR Shield, a product from its G2D NanoCORR line of anti-corrosion paints and coatings additives. Developed with its G2D technology, the product is a graphene-enhanced chemical additive designed to increase the corrosion resistance of solvent-based paints and coatings. NanoCORR Shield has demonstrated a 30-70% increase in corrosion resistance when subjected to salt spray testing.
The addition of a small amount of graphene — an ultra-strong carbon nanomaterial — into paints and coatings enables an increase in the barrier effect against corrosive elements such as water, oxygen and chlorides. NanoCORR reduces paint consumption by reducing the nominal thickness of the coating while maintaining the paint or coatings’ other characteristics and performance properties.
The product complements the company's line of chemical additives for the paint and coatings market. In recent testing, NanoDUR W102 demonstrated a 33% reduction in paint consumption and application, reducing the frequency of repainting by up to a third.
“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. Its positive impact goes beyond protection against corrosion, promoting sustainability and economic efficiency in multiple sectors,” says Alessandra Zanuto, technical manager of products and sales of chemical additives at Gerdau Graphene.
“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 at Gerdau Graphene.
