Nitofill UR63 is a two part solvent-free, low viscosity, polyurethane resin system. When mixed in the proportions supplied reacts to form a tough, slightly flexible resin. Nitofill UR63 has a good adhesion to concrete and masonry and when injected into cracks it allows some movement without loss of bond.
Used in conjunction with Nitofill WS60 forms a permanent seal in cracked concrete.
Low viscosity allows penetration into the finest cracks.
Formulated for hot climates/conditions. Good adhesion to dry or moist substrate.
Flexible to withstand differential movement.
Tough to sand up to high hydrostatic pressures.
Cures to an impermeable mass.
