Resfoam HB 45

Flexible, Hydrophobic Polyurethane Grout

Resfoam HB 45 is a low-viscosity, flexible, hydrophobic polyurethane grout used to stop water infiltration in concrete structures. Resfoam HB 45 is a solvent-free, MDI-based polymer system that reacts with water. Use Resfoam HB 45 together with Resfoam HBA 45 accelerator to adjust the reaction profile for a specific application. In a free-rise circumstance, Resfoam HB 45 will expand up to 750% of its liquid volume. Upon application, Resfoam HB 45 reacts to form a closed-cell polyurethane grout that will not shrink, and provides an elastomeric waterproof barrier sealing infiltration points against water intrusion. Resfoam HB 45 is nontoxic and has good chemical resistance.
