3M™ Connected Roads All Weather Elements consist of an outer layer of microcrystalline ceramic beads partially embedded into composite cores. These elements offer optimal performance under dry and wet conditions because of their unique combination of 1.9 and 2.4.

3M™ Connected Roads All Weather Elements features unique 3M™ Microcrystalline Ceramic Beads.  These make them more robust than conventional glass-beaded optics making them more resistant to wear and tear. Adding these optics into a thermoplastic line marking helped us meet the durability requirement of the specification.
