Guidelines for everyone, or zebras and other stripes
Lane markings on roads and highways need to be very robust. Today, Evonik supplies a group of reactive resins under the brand name DEGAROUTE that act as bonding agents and ensure the longevity and durability of road markings.
In order to align the cold plastic’s durability with the resurfacing cycle and to increase economic efficiency, there followed the development of cold spray plastic, with a layer depth of 0.3-0.8 mm and the application technology in cooperation with manufacturers of road marking machines.
Over the years, Degussa has developed different variations for different purposes: for example in 1988, a new profiled DEGAROUTE cold plastic marking compound was introduced. The advantage: the markings have profiles that stand out above the otherwise smooth marking at regular intervals, which makes the lane markings more visible through headlights in dark and wet conditions. Furthermore, driving over them makes a noise, alerting the driver to possible unintentional lane crossing. Road markings of this kind are known today as “Type II” markings. Low-noise versions are structural markings, called agglomerates, which have the advantage of being more resistant to snow ploughs and, owing to less material, are particularly economical.
Röhm, too, widened continuously its road markings range. In the construction chemicals segment this application was pivotal and in consequence was marketed together under the brand name PLEXILITH. Following the successful trials in 1982 using red bikeway coatings, coating resins gained importance.
In 1999 Röhm and Agomer (Degussa’s subsidiary for methacrylate activities) were merged. In consequence the methcrylate activities of both companies were consolidated. Today all road markings are concentrated under the Evonik brand name DEGAROUTE.
