SportBond UBN 5105

SportBond® UBN 5105 (formerly HBN 5105 and EB 01045-1) is a series of single-component, 100% solids, moisture-cured polyurethane binders that are designed for bonding particles together (typically crumb rubber). The resulting composites are used in the manufacture of running tracks, playgrounds, and other synthetic play-surfaces where energy absorption and other impact criteria are important. The cure profile of SportBond® UBN 5105 binders allow for either batch-mix or continuous application processes.
