Rocbinda™ is a two- part polyurethane resin system used to bond calcined bauxite aggregate to provide a Type 1 approved strong anti-skid surface. Its performance at TRL classified Rocbinda™ as excellent, and better than conventional epoxy formulations. Since 1999, Rocbinda™ has held a BBA / HAPAS certificate (12/H196), for Type 1 applications, the results of the independent testing proving it can withstand up to 3,500 commercial vehicles per lane per day braking on it, with an expected lifespan of five to ten years.
