We are thrilled to announce that our brand-new Research and Development Building is well underway! This state-of-the-art facility will provide our talented Team with the resources and environment to explore new horizons. With cutting-edge laboratories and collaborative workspaces, this new building is set to become a hub of creativity and technological advancement. Stay tuned for more updates as we embark on this exciting new chapter!
The use of ionizing radiation is an indispensable part of modern medical treatment. The use of radiation shielding apparel for the personnel in charge of these instruments is mandatory. For a long time, lead (Pb) was the go-to element. However, environmental concerns and the heavy weight of lead have prompted the search for alternatives. Antimony powder (Sb), bismuth powder (Bi), and their oxides have found widespread use due to their radiation high shielding performance.
Recent Chinese export restrictions on bismuth and antimony products have led to a significant increase in the prices of these raw materials. Prices for bismuth and antimony have multiplied in recent weeks, seriously impacting supply chains. As a result, alternatives are being revisited, bringing tin powder (Sn) and tin oxide (SnO2) back into focus. While the radiation shielding performance of tin powder or tin oxide is not as good as bismuth, it is comparable to antimony-based products, as shown by data from the NIST database.
Keeling & Walker offers cost-effective alternatives to expensive bismuth and antimony with their Superlite Tin Oxide and Black Tin Powder, providing comparable protection. For direct incorporation into polymers a Tin Oxide Master batch Irasorb MB620 is available.
Radiation Absorption of Tin and Tin Oxides over the radiation energy range
From 1 – 4th July 2025 the Ceramic Network Meeting will take place in Limoges, the heart of the French ceramic industry.
Keeling & Walker will take the opportunity and for the first time exhibit at the prestigious event organized by the Pole European De La Ceramique bringing together all important players in the area of technical and advanced ceramics in France and beyond.
Keeling & Walker looks forward to present its range of Tin Oxides and Functional Pigments for applications ranging from the decorative ceramics, friction materials and high end electronic materials. Special highlight will be the different grades of Antimony Tin Oxides for antistatic coatings and for Laser Direct Structuring as well as the range of high purity tin oxides for sputtering applications.
Keeling & Walker will be exhibiting at Ceramitec 2024 in April in Munich, the one of the most important European trade shows for ceramic materials.
Besides its extensive line of different Tin Oxide grades which are used as opacifiers or raw material for ceramic colour pigments or electroceramic materials, Keeling & Walker will also highlight its new products like Indium Oxide and Indium Tin Oxides.
Additionally the StanoStat range of functional pigments for Antistatic Glazes for floor tiles and ceramic Insulators will be shown. A very new use case of StanoStat additives are Laser Direct Structuring processes on ceramic substrates for electronic applications.

Keeling & Walker reduces its Carbon Footprint
Since yesterday Keeling & Walker is not only producing Tin Oxide and NIR Absorber but also electricity. The installation of the solar panels was finished and the unit was connected to the grit. On the roof of its factory building at Clarendon Street site a 49,5 kwp unit was mounted, which is projected to provide around 48.000 kWh per year. On its second day of operation the panels already provided more electricity than the Clarendon site did use. Keeling & Walker decided to install the solar panels not only for sustainability and a lower carbon footprint, but also for economic reasons. Given the recent turmoil in the energy markets, having a supply of energy at stable calculatable costs independent from the volatile market prices will provide a stabilizing and balancing effect on the energy bills. Ultimately this will benefit Keeling & Walker´s customers as increasing energy costs and especially their spikes can be buffered to a certain extent. In that respect the solar panels will make a contribution to improve Keeling & Walker´s competitiveness. What can better than making a positive impact on the company´s environmental footprint and at the same time improve its economic situation?

CodiKoat, BDK and Keeling & Walker team up to develop a transparent, self cleaning, antimicrobial protective coating
Cambridge Biotech firm CodiKoat have developed a self-cleaning protective coating that can help clean up “filthy” public touchscreen devices and protect against viruses.
From supermarket checkouts to cash machines and public transport, there is a growing reliance on self-service and touchscreen machines in our daily lives.
These devices can be used thousands of times per day but even the most robust cleaning procedures still rely on human intervention. Constant re-sanitisation is a serious resource-drain for businesses, who could not possibly hope to clean the devices after every use.
CodiKoat have developed a groundbreaking antimicrobial protective coating that uses nanotechnology to remove 99.9% of harmful bacteria and virus particles from surfaces within seconds of contact.
The remarkable coating is self-cleaning and incredibly durable, offering the same outstanding ongoing protection for users no matter how frequently it’s used.
Best of all, it can be applied easily to any touchscreen device via a transparent adhesive film, or be implemented straight into the manufacturing process – with no drop in touchscreen performance.
To help bring this amazing coating to the masses, CodiKoat have entered into a partnership with two world-leading UK-based manufacturers.
Keeling & Walker will produce specialist pigments that will form part of the protective coating, while BDK will lead on printing and producing the adhesive film.
A prototype of the adhesive film product was previously tested at London’s Royal Opera House, where a pilot scheme saw samples touched over 2 millions times over three months, with no drop in its antiviral capabilities.
Partnering with both BDK and Keeling & Walker, the aim is to now produce a fully transparent adhesive film that will offer the same incredible protection and not interfere with the displays of touch screen devices.
CodiKoat Co-Founder Payam Nahavandi said, “We’re thrilled to be taking on this challenge with incredible partners like BDK and Keeling & Walker. These devices are used millions of times per day globally and we believe this development can help protect the public and reduce the resource strain on millions of businesses worldwide”.
BDK`s Director Nick Falconer said, “We are very excited to work with the CodiKoat team on a groundbreaking global solution to help clean up the world!”
Dieter Guhl, Managing Director of Keeling & Walker added, “We look forward to a successful cooperation with CodiKoat and BDK to create a highly functional solution for a cleaner and safer environment”.
