Henning Schulze founded the chemical factory A.I. Schulze Chemotechnische Fabrik for the German market in 1952. The cooperation with the commercial agency D. Bartkowiak Vertriebs- und Logistikzentrum in 1988 led to the establishment of a network of foreign General Agencies which played a significant part in the worldwide product launch of BIRKOSIT Dichtungskitt®.
The two companies have been operating as a single unit since 2008 and are coordinated by shared headquarters. » History

The transfer of know-how within our group of companies is the means whereby we set standards worldwide, not least in this respect.”
