Swiss specialty chemicals producer Clariant has completed its acquisition of de-icing chemicals producer Aerochem, based at Stockholm, Sweden, for an undisclosed sum.

The Swedish firm, which claims to have a leading market position in supplying de-icing fluids to the aviation and railway industries in Sweden, Norway and Denmark, has annual sales of around 20 million Swiss francs.

Since 2008, Aerochem has been Clariant's exclusive partner for selling aircraft de-icing fluids to customers in the Nordic market.

Clariant will integrate the acquisition into its business unit Industrial & Consumer Specialties, which claims a leading position in the aviation industry in Europe and North America.

"The acquisition is in line with our growth and sustainability strategy," said Hariolf Kottmann, CEO of Clariant. "Aerochem offers access to the attractive de-icing markets in the Nordics and provides an excellent platform for our activities in recycling of aircraft de-icing fluids in Europe."
