The Pacific Northwest Snowfighters approved Headwaters Corrosion Inhibitor at a 3.5% application rate (dose rate) to reduce the corrosiveness of salt brine (23.3% sodium chloride solution) by 75%. Compared to inhibitors that must be applied at a 5% dose rate, the biodegradable additive saves 30% on transportation and storage by reducing the amount of water that must be shipped. It is also free-flowing and stable in cold temperatures, making it easy to handle. Rivertop Renewables.
