SCHLENK

Based in Roth, Germany, SCHLENK is a historic industrial enterprise that specializes in the development and manufacture of metal powders, pigments, and foils. Founded in 1879 by Carl Schlenk, the company has remained a family-owned entity for over a century, evolving from a local bronze powder producer into a global materials science organization. While its operations span various industrial sectors, the company plays a specific and critical role within the maritime and offshore industries as a key upstream supplier of high-performance protective materials. In the context of marine engineering and shipbuilding, SCHLENK is recognized for its advanced metallic pigment technologies, which are essential components in the formulation of heavy-duty marine coatings. The harsh operating environment of the open ocean, characterized by constant exposure to saltwater, humidity, and UV radiation, demands robust defense mechanisms for steel structures. The company addresses this challenge by producing specialized zinc and aluminum pigments designed to extend the service life of vessels and offshore platforms. The company’s zinc flake pigments are particularly significant for the maritime sector, as they provide cathodic protection - a sacrificial mechanism that prevents the corrosion of the underlying steel hull or structural component. Additionally, their lamellar aluminum pigments are engineered to create a barrier effect within paint systems. When applied to ship hulls or superstructure elements, these overlapping metal flakes form a dense shield that significantly elongates the diffusion paths for moisture and corrosive ions, thereby delaying degradation. Operational capabilities support this specialized maritime supply chain through a network of production facilities across Europe, the United States, and Asia. This global footprint allows the company to supply international paint manufacturers with the raw materials needed to produce primers and topcoats capable of withstanding extreme marine conditions. Beyond standard corrosion protection, the company’s research into material functionalization continues to support the development of thinner, more efficient coatings that contribute to fuel efficiency and reduced maintenance intervals for shipping fleets. Through its focus on the fundamental science of metallic particles, SCHLENK remains a foundational pillar in the effort to preserve maritime assets against the elements.
