    MasterFiber MAC 2200 CB: Synthetic macrofiber with chemical bond for low deflection applications

    How does MasterFiber MAC 2200 CB work?

    MasterFiber MAC 2200 CB product is a chemically enhanced synthetic macrofiber that exhibits superior bonding to cementitious matrices, thus increasing the post-crack load-carrying capacity and toughness of fiber-reinforced concrete. The superior performance of MasterFiber MAC 2200 CB product results from a novel polymer resin technology that provides engineered chemical bonding, a technology breakthrough from BASF. Through this advanced technology and a highly engineered fiber architecture, the bonding capabilities of MasterFiber MAC 2200 CB product far exceed that of the other commercially available polyolefin-based synthetic macrofibers.

    Recommended uses:

    • Cast-in-place and wet precast concrete
    • Slab-on-ground
    • Bridge decks
    • Concrete pavements
    • White topping and overlays

    What are the unique features of MasterFiber MAC 2200 CB?

    • Chemically enhanced to provide superior performance as compared to typical high performing synthetic macrofibers.
    • Engineered for use as secondary reinforcement to control shrinkage and temperature cracking and to provide performance equivalent to that of other commercially available synthetic macrofibers, at a reduced dosage.
    • Reduced dosage will result in improved handling properties in the fresh state, as well as, improved finishability.
    • The unique packaging helps to promote even distribution and optimal dispersion of fibers in concrete mixtures.
    • Created specifically to replace welded-wire reinforcement and No. 3 and No. 4 (10 mm and 13 mm) reinforcing bars that are typically used as temperature and shrinkage reinforcement.

    What are the beneifts of MasterFiber MAC 2200 CB?

    • Provides post-crack performance equal to that obtained with typical, commercially available synthetic macrofibers at a reduced dosage
    • Improves placement and finishing characteristics compared to traditional synthetic macrofibers
    • Eliminates the need for welded-wire reinforcement (WWR) and conventional steel bars as secondary reinforcement, depending on the application
    • Utilizes an advanced packaging system that improves dispersion, reduces storage footprint and increases bags per pallet, thus optimizing pallet’s capacity
    • Reduces construction time and overall labor and material costs
