In the Northern hemisphere, the maintenance of runways is a demanding task for airports. A safe take off and landing must be guaranteed even in case of black ice and snowfall so de-icing must be efficient, fast, and unfailing.
Sales Manager Timo Nissinen says that nowadays the safety aspect is increasingly combined with a strong environmental standpoint when it comes to de-icing chemicals. "The previously widely used urea was banned a decade ago for environmental reasons. This stimulated chemical suppliers to develop new alternatives for de-icing."
The Clearway product family has been in Kemira's product portfolio since 2005. The acetate and formate based chemicals are suitable everywhere where there is a need for the prevention and melting of ice and snow. "Clearway products are currently in use at airports in Europe, Russia (CIS area), and Japan," Nissinen recounts.
