Aalter police cars have striping with Sioen technology

The municipality of Aalter recently presented the first police vehicle with Sioen Chemical’s new generation of UV-inks and protective varnish. The new police cars will be put into service by the end of 2020. It might seem as if the vehicles’ appearance doesn’t change much. At night, however, the striping’s reflection is three times better than regular ones, improving the officers’ visibility and safety.

Kurt Troch, R&D Manager Radiation Curing at our Sioen Chemicals Division: “Our customer OTM asked us to develop a new generation of UV-inks for super reflective sheets to improve the visibility and security of policemen.” He adds that their biggest challenge was to obtain the best adhesion with corresponding resistances combined together with maintaining the transparency with respect to the colour references of the tender’s specifications.

The final result is a striping of which the reflection is three times better visible than when using a regular striping. In addition, the striping also shows outstanding weather, chemical and mechanical resistance properties, thanks to its polymerisation. It is also easy-to-handle, no volatile solvents were used and after exposure to UV-light, the film is dry immediately.

Even though the innovative striping is new, our radiation cured inks on “standard” reflective sheets aren’t new. Most Belgian police vehicles are printed with our inks for more than 17 years now. What’s more, all official license plates have been printed with Sioen’s inks for more than 10 years.

U.C.S. is part of the Sioen Chemicals Division and is specialised in formulating and producing tailor-made radiation curing inks and varnishes for graphical and industrial applications used with printing techniques, such as screen printing, roller coating, gravure or digital printers.

Radiation curing products - inks, varnishes and primers - will change from liquid state to solid state after exposure to energy-rich radiation. In general there is no physical drying involved, the crosslinking is initiated by UV-light, Led-light or Electron beam.
