What Weiss Chemie does

Weiss Chemie + Technik GmbH & Co. KG is a German, family-owned industrial manufacturer founded in 1815, specializing in adhesives, sealants, and composite sandwich panels sold under the COSMO brand. The company operates three production facilities in Germany — Werk I in Haiger (headquarters), Werk II in Herzebrock, and the Pudol site in Niederdreisbach for cleaning and care products — and maintains a North American subsidiary (Weiss USA). Its product portfolio comprises more than 400 variants of adhesives (1-K-PUR, 2-K-PUR, cyanoacrylate, hybrid/MS polymer, diffusion, epoxy, and dispersion), primers, cleaners, biobased adhesives, and special solutions, alongside more than 5,000 sandwich panel configurations spanning COSMO Therm, Silent, Protect, Tech, Design, and Frame sub-brands with facing materials including GFK, aluminum, HPL, PVC, and plywood, and core materials including XPS, PUR, and thermoplastic (TK).

The business model is sales-led B2B with direct customer engagement by technical and commercial specialists who provide application technology consulting, custom adhesive development, quality assurance, and logistics support. Products are sold via the company's own direct sales force and regional contacts (Germany, Spain/Portugal, Poland, the US) with no disclosed distributor or reseller network, and pricing is quote-based rather than publicly listed. End markets include window and door manufacturers, commercial vehicle and trailer builders, container manufacturers, fire-protection door producers, flat-roof contractors, RV/caravan makers, partition wall builders, woodworking/furniture, and general industrial assembly. The company holds certifications including GEV EMICODE EC2, French VOC emissions Class A+, and ILAK salt spray testing per DIN EN ISO 9227, and has recently launched new products (COSMO HD-200.101, COSMO HD-120.150) and signed a letter of intent to add a production facility in China to support further geographic expansion.

Ownership rests with the personally liable partner WBV - Weiss Beteiligungs- und Verwaltungsgesellschaft mbH, a holding entity, with Christian Dölle as CEO (Geschäftsführer); the company is privately held with no external private equity or venture capital backing disclosed. Marketing is conducted through a multilingual website (10+ languages), LinkedIn, Instagram, YouTube (Weiss Chemie TV), newsletter, and trade fair participation. No public revenue, headcount, or funding figures are disclosed; the only headcount figure available (5) is inconsistent with the operational footprint described and should be treated as unreliable.

Core offering

Weiss Chemie manufactures and sells two integrated product families under the COSMO brand: industrial adhesives and sealants (more than 400 variants of 1-K-PUR, 2-K-PUR, cyanoacrylate, hybrid, diffusion, epoxy, and dispersion adhesives, plus primers, specialty cleaners, and biobased options) and composite sandwich panels (more than 5,000 configurations across the COSMO Therm, Silent, Protect, Tech, Design, and Frame sub-brands). The panels are manufactured using Weiss's proprietary in-house developed adhesive systems to bond facings (GFK, aluminum, HPL, PVC, plywood) with cores (XPS, PUR, TK) for industrial applications.
