SportBond UBN 5105-3

Isotec’s SportBond® UBN 5105-3 (Formerly IsoBond HBN 5105-3, IsoBond EB01045-25 and EB01045-25) 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 5105-3 binders allow for either batch-mix or continuous application processes.
