NautiChem GmbH is a German company known for high quality military grade sealants and adhesives. Formerly known as Paul Pietzschke, the company was founded by its namesake in 1889 at Hamburg, Northern Germany. From the very beginning, this chemical and technical company has endeavored to produce and market a line of high quality elastic sealants, coatings and lubricants for the ever-growing global commercial marine market.

The Pietzschke line of products quickly established themselves by meeting the rigorous demands of the commercial ship building industry. As a result, Pietzschke Supra Marine Glue soon became the default standard for the caulking of wooden deck joints. In addition, the Pietzschke line of Launching Grease is renowned for its consistently reliable performance.
