Additional Details

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.

Applications

  • To protect saw-cut crack-control joint edge shoulders from forklift damage
  • Interior warehouses, distribution centers, convention centers, arenas, grocery and retail stores with exposed concrete
  • Highly suitable for use in high traffic areas where maximum impact resistance and joint edge shoulder protection is required
  • In refrigerated or freezer environments
  • To fill keyed or doweled construction joints and repair cracks or small joint edge fractures
