HAERTOL is a German company through and through. VEB Härtol Werk was founded in Magdeburg in 1952. Over the course of the 1970s and 1980s, it developed into one of the largest producers of chemical products in the former GDR — leading in the manufacture of antifreeze, soldering supplies, surface finishing pre-treatment products, flux for hot-dip galvanization, quench salts and quench oils.
After reunification, Härtol GmbH Magdeburg was acquired by Henkel KGaA Düsseldorf. In the year 2000, HAERTOL Chemie GmbH went back to being an independent and owner-led company. Since 2019, Dr. Marco Bergemann has been Managing Partner. In 2023, the US group Valvoline Global Operations acquired a stake in HAERTOL.
