Properties

• Up to 90 % reduction of fine dust emissions caused by brake discs
• Corrosion-free, even in recuperation operation (electric vehicles)
• Service life over the entire car life cycle possible
• The WECODUR coating system can be applied to ANY conventional brake disc without any special pre-treatment
• Low additional costs compared to a conventional brake disc
• Drastic cost reduction compared to other coating processes for brake discs
• WECODUR-coated brake discs pass common tests in the automotive industry

Reduction of fine dust emissions

The sources of mobility-related particulate matter pollution come essentially from three sources: Combustion residues, abrasion from tyres, brakes and road, and the whirling up of already deposited particulate matter. According to a study by the Federal Environment Agency, Germany particulate matter from combustion residues has been significantly reduced by stricter emission standards and vehicle modernization and is expected to continue to decrease, e.g. through the expansion of electric mobility. In contrast to that, the abrasion of roads, tyres and brakes has not been reduced to date. However, it is precisely here that the further savings in particulate emissions must be realized. WECODUR coating systems provide significant improvements of up to 90% in the field of brakes. Due to the large scale production process, area-wide application is possible for the first time.
