Corrosion Testing
(3% Solution)
The graph above shows corrosion rates of various common deicers as conducted from the NACE Standard TM0169-95 (1995 revision) and as modified by the Pacific Northwest states (test material used was a non-galvanized flat steel washer). Cryotech NAAC exhibits much lower corrosion rates than chloride-based products and for this reason NAAC should be used in place of chloride deicers.
Corrosion testing using steel plate (JIS G 3141 cold rolled steel plate) was performed, and steel plate corrosion rates were obtained. The corrosion rates of deicers containing only an acetate compound caused almost no corrosion, this includes sodium acetate. The corrosion rates of sodium chloride and calcium chloride were between 80 to 90 mdd (milligrams of weight loss per square decimeter per day). Among the mixtures including a chloride substance, the corrosion rate of the mixture of urea and sodium chloride was highest at 130 mdd.
