Keeling & Walker

What Keeling & Walker does

Keeling & Walker Limited is a UK-based specialty chemicals manufacturer founded in 1916 and headquartered in Stoke-on-Trent, England. The company is a subsidiary of Amalgamated Metal Corporation PLC (AMC Group), having joined the group in 1964. It self-describes as the world's largest producer of tin oxide materials and offers over 50 differentiated grades organised across the Superlite, Thermox, and high-purity (99.99%+) product families. Its manufacturing relies on proprietary thermal oxidation processes — the Superlite process (foundation developed 1932) and the Thermox process acquired from Th. Goldschmidt AG in 1998 — together with a patent-protected doped tungsten oxide technology (Irasorb CTOM10) and a proprietary nanodispersion process that yields virtually salt-free transparent dispersions (10-20 nm particle size, ATEX-rated facility opened 2025).

The product portfolio extends beyond tin oxide into antimony tin oxide (StanoStat CP/CPM), indium tin oxide (Irasorb YITO, BITO), tungsten oxide NIR absorbers, and specialty metal chemicals (FTO, precious-metal-doped tin oxides, high-purity indium oxide, indium nitrate solution, calcium copper titanate). These serve four primary end markets: ceramics and glass; electrical and electronic applications (silver-tin oxide contacts, sputtering targets, transparent electrodes); polymer additives (laser marking, laser direct structuring for 3D-MID, antistatic, NIR absorption); and inks and coatings (antistatic, transparent conductive, solar protection). Customers include approximately 200 companies in more than 30 countries, qualified under continuous ISO 9001, ISO 14001, and ISO 50001 certification.

The business model is industrial B2B with quote-based pricing, EXW (Ex Works) terms, and 30-day payment. Commercial reach is delivered through direct enterprise sales and a multi-distributor architecture — DKSH for 19 European markets, WPS S.r.l. for Italy, Radiance Biosynthetics for India, and a China exclusive agent — supplemented by active participation in more than 15 global trade shows annually (K-show, Ceramitec, Chinaplas, LOPEC, European Coatings Show, PLAST, etc.). Recent strategic emphasis has been on extending geographic reach into Asia and the Americas, co-developing new applications (CodiKoat antimicrobial touch coatings, 3D-MID LDS additives), and commercialising higher-value nanodispersions through the new 2025 R&D and manufacturing facility.
