DuPont Coating Solutions has introduced Alesta ZeroZinc primer, an anti-corrosion powder coating system designed to combine protection in severe climatic and environmental conditions with greater environmental safety.

The zinc-free, anti-corrosion, chemical-resistant, epoxy primer has been developed to protect ferrous metals against corrosion in a wide range of environments, from heated building interiors to external industrial areas with high levels of humidity and pollution—environments often classified from C1 to C5-I, according to ISO 12944.

Features and Specifications

The system is formulated with High Density Crosslinking (HDC) technology to strengthen the primer’s barrier effect and create a completely sealed, flexible coating that resists impact and adheres well.

With proper preparation and application, the coating isolates the steel from its environment and provides durable corrosion protection, even under the most severe conditions, for at least 15 years, the manufacturer says.

Alesta ZeroZinc primer

Free of zinc and heavy metals, Alesta ZeroZinc lacks the abrasiveness that leads to wear on equipment and is designed to satisfy environmental legislative demands, according to the manufacturer. The primer can be recycled, and its low density improves efficiency as more square meters per kilo can be coated, according to DuPont.

Application

The protective layer is easily overcoated with powder and liquid topcoats within 12 hours without sanding or any other preparation and cures within minutes.

Applications include general construction such as metal structures, iron work, the transportation industry and industrial machinery.
