Russian scientists develop sealant for Arctic ships and aircraft
Scientists from the RT-Chemcomposite holding company, a Rostec subsidiary, have developed a highly durable sealant for ships and aircraft. The new substance can withstand both subzero Arctic temperatures and stifling hot weather.
"The acrylic polymer is used to fix and seal smooth and threaded joints during the assembly of crucial units and systems used in shipbuilding, aerospace, engineering, oil and gas and other strategic industries," the RT-Chemcomposite press service said in a statement.
According to the developers, the sealant's distinctive feature is that it remains effective during peak loads and high vibration levels, as well as high and subzero temperatures, including the Arctic climate (from minus 60 degrees Celsius to plus 150 degrees). It is also resistant to various chemicals, including oils, fuel and antifreeze, solvents, thinners, acids and alkali.
The Anaterm-527 sealant was developed by experts from the Research Institute of Polymers, an RT-Chemcomposite subsidiary, under an import substitution program aiming to replace the Loctite 577 sealant, manufactured by Germany's Henkel and currently used in the Russian industry. The new unique Russian-made material costs 15-20 percent less than its foreign equivalent.
According to corporate sources, the sealant has already been tested at automotive giant AvtoVAZ and engineering companies manufacturing railroad transport products and equipment for oil and gas wells.
