SportBond UBN 5105-3

SportBond® UBN 5105-3 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.
