Sachtleben Launches Security Marking Solution
Germany-based Sachtleben Chemie GmbH — a producer of titanium dioxide pigments, polyaluminum
chloride flocculants, and barium sulfate and zinc-based functional additives, and a company of
Rockwood Holdings Inc. — has created a marking system that provides permanent protection for
intellectual property and can only be detected using special analytical procedures.
The security particles can be either applied in a pure, isolated form or adapted individually to customers’ specifications, such as incorporation into an additive or into compounds and masterbatches. The particles are chemically and thermally stable and can withstand processing such as extrusion without being damaged or modified.
Potential applications include textiles, plastics, pharmaceuticals, cosmetics, printing inks and security papers, among other uses. A low input quantity of the particles is needed to provide a high level of anti-copying security.
Sachtleben is working with external service providers to offer the analytical services needed for detecting the marking substance; however, the company notes that the analysis is not always necessary to check production. Following a training course, users can easily perform production checking using their own analytical methods.
