The Dow Chemical Co. (Ludington, Michigan) has introduced a corrosion inhibiting deicer for use in highway anti-icing applications, as well as for rock salt, and abrasive pre-wetting and stockpile wetting applications.

The material has passed corrosion performance tests and proved less corrosive to vehicles and highway snow removal equipment than ordinary rock salt, according to Gerry Matthews, Dow North American industry manager.

The Deicer exceeds corrosion specifications developed by NACE International Standard TM-01-95, as modified by the Pacific Northwest States Coalition (PNS) and other agencies. A corrosion value of less than 70 per cent is considered passing.

The deicer has the ability to remain in liquid form at temperatures as low as –27°C, the company reports, and does not contain insoluble impurities such as sulphates, camallite, and other by-products found in other deicers.

When used as an anti-icing agent on roadways, the recommended application rate of the deicer is 20-50gal per lane mile. Lesser amounts are used to control frost and black ice conditions. As a pre-wetting agent, the chemical typically is applied at a rate of 6-10gal per ton of material.
