Schlenk

What Schlenk does

Schlenk (legal entity SCHLENK SE, formerly Carl Schlenk AG) is a privately held, family-owned German specialty materials manufacturer founded in 1879 in Roth-Barnsdorf and currently in its fourth generation of family leadership under CEO Joachim von Schlenk-Barnsdorf. The company operates three core product platforms — effect pigments, metal powders, and metal foils — using proprietary processes including wet milling of atomized aluminum, vacuum metallization (Decomet®, since 1994), ultra-thin pigment technology (Zenexo®), and high-precision rolling of copper, nickel and silver alloys down to 6 µm. It serves industrial B2B customers in over 100 countries across automotive coatings (OEM and refinish), industrial coatings, printing inks, plastics, cosmetics, powder metallurgy, construction materials, chemicals, batteries, photovoltaics and power electronics.

The company's go-to-market is direct enterprise sales through Area Sales Managers and local representatives, supported by wholly-owned production and sales entities in Germany, the USA, the Czech Republic, Slovenia and Italy. Pricing is quote-based and negotiated, typically under multi-year contracts, with no public price list. Schlenk's competitive position rests on patented technologies (Zenexo®, LHS), a deep portfolio of registered brands (Decomet®, Zenexo®, Metaprint®, Rogal®, Cubrotec®, MultiFlect®, AluStar®, Alumer®, AluMotion®, HTA), 145 years of accumulated process know-how, and ISO 9001/14001/50001 certifications across multiple sites.

Recent strategic emphasis is on advanced battery materials (HTA high-tensile copper foils, 10 µm Al-Cu roll-clad foils for bipolar/SSB batteries, battery tab ribbons), photovoltaic connectors (LHS), and a new entry into power electronics via CuNex copper sinter paste developed in partnership with CuNex GmbH (THI Ingolstadt). The Metal Foils Business Unit (~120 employees) was reorganized with management relocated from Barnsdorf to Bernlohe, and a new Managing Director was hired from Heraeus's solar pastes unit, signaling a deliberate push into energy-related specialty foils.
