When use Liquid E36 and when Solid NAAC deicer?
Cryotech manufactures and markets both solid and liquid runway deicers. Both are acetate-based and easily biodegrade, they are considered safe for the environment. They serve complimentary purposes during airport winter operations. Liquid E36® (potassium acetate) is generally used as an anti-icer to prevent snow and ice from bonding to the surface. The snow and ice can then be easily removed by broom or plow. Solid NAAC® (sodium acetate) is used as a deicer. It is also applied early in the storm but its purpose is to melt through an existing pack and break ice-to-pavement bonds prior to mechanical removal. E36 is more efficient than a solid deicer when applied as an anti-icer because it takes less energy to prevent surface bonding than to break existing bonds. Therefore, early liquid application followed by mechanical removal of snow and ice accumulation provides the best and most efficient method for combating winter storms. “Early application” means applying just before the event or
