The foundation stone for the company's reputation was laid on May 10, 1879, by master plumber Wilhelm Paff, who developed, manufactured and distributed soldering water in addition to his craftsmanship. His successor Hans Eckstaedt, the son-in-law of the company founder, successfully led the expansion and established the internationally protected trademark Stannol in the market at the end of the 1920s . Already in the fifties Stannol started to develop products for electrical engineering and later also for the electronics industry. In 1989, Stannol was acquired by the English concern Kelsey Industries, with its own offices in the United States, Canada, Australia and Malaysia. In February 2000, Kelsey Industries was acquired by Henkel KGaA. The following year was marked by restructuring. For example, some product areas had to be transferred to Loctite Deutschland GmbH, a Henkel subsidiary. In July 2001, Karl-Heinz Dörr, as former managing director, took over the Stannol soldering mill Wilhelm Paff GmbH & Co. KG, which now now operates under Stannol GmbH & Co. KG, as part of a management buy-out. In 2017, Marco Dörr becomes managing director at his father's side and takes over most of his duties.
