Founded in the early 1900s, Keeling & Walker Limited is a global manufacturer of tin oxide-based materials, including a range of functional pigments and nanomaterials.
Keeling & Walker has developed a range of IR-absorbing pigments used for laser marking of polymers, laser direct structuring of plastics or as process additive for plastics as well as additive for powder sintering processes in 3D printing. Doped tin, tungsten and indium oxides are available under the trade names StanoStat and Irasorb.
The company endeavors to deliver the products in a form that is adapted to the processing conditions. Self-dispersing nano-pigments are offered for the plastics industry, with which it is possible to produce transparent films or sheets directly in an extrusion process.
