Dynaflex JF-85 is a fast-setting, tough, semi-rigid, two component, 100% solids, polyurea, industrial concrete joint filler with a Shore A Hardness of 85. Dynaflex JF-85 is specifically formulated to support heavy loads without deflection, protecting joint edge shoulders from potential spalling. This joint filler is ideal for environments with frequent forklift use, as it supports and absorbs high-impact wheel traffic. Dynaflex JF-85’s factory proportioned mixing ratio eliminates potential measuring errors and removes a step from the process, allowing projects to function more efficiently. There's a reduction in waiting time, too, because Dynaflex JF-85 sets fast and shaving can take place as early as 2 hours after installation.
