According to the manufacturer, a water-based coating is the first to withstand a minimum of 1,000 hours of intense salt spray at a 0.001" coverage rate.

Cortec Corp., St. Paul, Minn., says its EcoShield 386 coating can protect metal structures in harsh outdoor conditions. A high gloss clear coat permits visual inspection of the substrate. Applications for the coating include industrial, energy, automotive and oil and gas.

The acrylic-based formula uses a mixture of nano-sized nontoxic organic inhibitors. It has achieved reproducible corrosion protection results on carbon steel panels according to the ASTM B117 standard. During testing at Cortec’s ISO 17025-accredited lab, the carbon steel panels were protected from the corrosive effects of continuous salt spray for days with a 0.001" DFT coating of EcoShield 386.
