What Woellner Holding GmbH & Co. KG Dr. does

Wöllner GmbH is a German specialty chemicals manufacturer founded in 1896 by Eduard Wöllner in Ludwigshafen am Rhein, now in its fourth generation of family ownership and managed since 2009 by the Dr. Eduard Wöllner Family Foundation. The company develops and produces soluble alkali silicates (waterglass), specialty silicate-based binders and adhesives, and process enhancement chemicals, organized into three main product lines: CCC (Coating & Construction Chemicals, with sub-brands Betol®, Betolin®/Sapetin®/Sikalon®, Collosil®, Geosil®, Ligasil®/Stabisil®), PEC (Process Enhancement Chemicals for industrial water circuits and the pulp and paper industry, including Warosit® and Verisil®/Sapetin®), and ISD (Industrial Silicates & Derivatives for large-scale chemical industry use). A newer addition, Waropure®, applies probiotic bacteria to biologically purify industrial cooling and process water circuits as an eco-friendly alternative to chemical biocides.

The company operates three production sites—Ludwigshafen (headquarters), Bad Köstritz (Thuringia, established 1993), and Gratwein-Straßengel, Austria (established 2002 as Wöllner Austria GmbH)—and employs approximately 150 people across these locations. Its customer base spans the chemical processing industry, construction chemicals and coatings, paints and plasters, pulp and paper, foundry and refractories, civil engineering, and industrial water treatment. The company holds in-house R&D, analytics, and microbiology laboratories, and supplies application-engineering support, dosing equipment installation, and on-site technical service alongside its products.

Wöllner operates a sales-led, direct B2B model through a specialized technical field-sales force serving commercial customers only, with quote-based pricing and multi-year industrial supply contracts; distribution in selected geographies is handled via channel partners such as Xatico Group Sàrl for Coating & Construction Chemicals in France. The company is privately held, with no public revenue disclosed; current Managing Director is Dr. Barbara März. Wöllner holds ISO 9001, 14001, 45001, and 50001 certifications, has maintained EcoVadis Gold status (top 5% of chemical industry firms assessed) since 2021, and was awarded the Rhineland-Palatinate Innovation Award 2024 for the Waropure® technology.

Core offering

Wöllner manufactures and sells soluble silicates (waterglass), specialty silicates, process enhancement chemicals, and biological water treatment solutions for industrial customers. Its three core product lines are CCC (Coating & Construction Chemicals), PEC (Process Enhancement Chemicals), and ISD (Industrial Silicates & Derivatives), with the Waropure® biological water purification range offered alongside. Products are sold primarily through a dedicated technical sales force to industrial buyers in chemical processing, construction, paint, paper, and water treatment sectors.

Product overview

Wöllner GmbH is a specialty chemical company offering three main product lines: CCC (Coating & Construction Chemicals), PEC (Process Enhancement Chemicals), and ISD (Industrial Silicates & Derivatives). The CCC line includes five sub-brands (Betol®, Betolin®/Sapetin®/Sikalon®, Collosil®, Geosil®, and Ligasil®/Stabisil®) providing silicate-based binders, adhesives, and additives for construction, coatings, and industrial applications. The PEC line features Warosit® process chemicals for industrial water treatment and paper production, plus Verisil®/Sapetin® specialty silicates for deinking and pulp bleaching. The ISD line offers standard waterglass products for large-scale chemical industry applications. An additional product, Waropure®, provides biological water purification using probiotic technology. The company also delivers technical services including dosing system planning, laboratory testing, and process optimization support.

Regional players

• Zschimmer & Schwarz: Zschimmer & Schwarz is a German family-owned specialty chemicals manufacturer producing silicates, phosphates, and custom chemical formulations for ceramics, textiles, and industrial applications. It is a comparable regional German peer with similar mid-market family-ownership positioning to Wöllner.

Direct peers

• Ciech Group: Ciech is a Polish specialty chemicals producer with a dedicated silicates business (sodium and potassium waterglass) serving paper, detergents, construction, and chemical industries across Europe. It is one of Wöllner's closest European direct competitors in soluble silicates.
• Kemira: Kemira is a Finnish specialty chemicals company focused on pulp and paper chemicals, water-intensive process industries, and water treatment. It is a direct peer to Wöllner's PEC line, especially Warosit® and Verisil® offerings for pulp bleaching and water circuit treatment.
• PQ Corporation (Ecovyst): PQ Corporation, now operating as Ecovyst after spinning off its performance chemicals business, is the largest global producer of soluble silicates (waterglass) and specialty silicas. It is the most direct comparable to Wöllner's ISD product line and competes in similar downstream applications including precipitated silicas, zeolites, and coatings.
• Tokuyama Corporation: Tokuyama is a Japanese chemical company with a long-standing soluble silicate and specialty silica business, supplying similar end markets (detergents, paper, construction, electronics). It is a direct global peer to Wöllner's ISD and specialty silicate product lines.
• Solenis: Solenis is a US-headquartered specialty chemicals company serving paper, pulp, and water-intensive industries with process and water treatment chemicals. It is a direct competitor to Wöllner's PEC product family in the European paper and industrial water treatment markets.
• BK Giulini (ICL Group): BK Giulini, now part of ICL Group, produces specialty silicates and phosphate-based binders serving construction, paper, and industrial applications. Its product portfolio and customer verticals closely overlap with Wöllner's CCC and PEC lines.

Broad incumbents

• Evonik Industries: Evonik is a major German specialty chemicals company with silica, coating additives, and construction chemistry businesses. It serves overlapping end markets with Wöllner but is many times larger and operates across a broader specialty chemicals portfolio.
• BASF: BASF is the world's largest chemical company and produces soluble silicates, precipitated silica, and construction chemicals as part of a much broader portfolio. It competes with Wöllner across multiple product lines but does not specialize in silicate chemistry.
• Wacker Chemie: Wacker Chemie is a German specialty chemicals company with overlapping silicates, silicones, and polysilicon businesses. While a broader player, it serves many of the same industrial verticals (construction, paper, coatings) as Wöllner and competes in adjacent specialty silicate niches.
