HYDRO ACTIVE® Multigel NF
HYDRO ACTIVE® Multigel NF is a hydrophilic polyurethane designed to react with water and form a water impermeable gel mass. HYDRO ACTIVE® Multigel NF is a pale yellow, nonflammable liquid. When it comes into contact with water, the grout begins to foam or gel, and depending on the temperature and amount of water present, quickly cures to a flexible, impermeable foam or gel mass unaffected by mildly corrosive environments. Cure times can be modified using accelerator (Flexgel Cat W) and gel strength can be increased using reinforcing agent.
