NCL SW-PU V Single-Component Flexible Injection Resin

NCL SW-PU V Single-Component Flexible Injection Resin Single-component Injection Resin NCL Injection Resin


NCL SW-PU V is a ready-to-use hydrophobic hydroactive single-component flexible Polyurethane injection resin specially designed for permanent sealing of water leakages on vibratory structure. It is suitable for sealing all type of leaking concrete defects especially live cracks, movement joints and other imperfection that caused water ingress.

NCL SW-PU V is fast reacting to water. It is moisture sensitive and reacts rapidly in contact with water to foams a permanent flexible watertight seal. Due to its resilient flexibility, it allows and absorbs movement from concrete structure e.g. parking area, tunnel, track bed, under-construction building etc.

Once cured, NCL SW-PU V remain permanently flexible and forms an excellent water-impermeable barrier against moisture and water infiltration.


NCL SW-PU V is a single component Polyurethane Injection Resin based on methylene diphenol isocyanate and polyether polyol. It is ready-to-use, no mixing is required.

It is recommended to keep container tightly closed in a cool (20 - 25°C), dry and well-ventilated place. Partly used drums/pails should be properly sealed to prevent ingress of moisture. To increase the material life expectancy, partially used drum/pail can be filled with nitrogen gas and sealed tightly to prevent contamination. When the material is stored properly, the shelf life is approximately twelve (12) months from the production date.


Waste disposal should be in accordance with all applicable local and national regulations. Kindly check with the local authorities on proper disposal method. Empty drums/pails should be punctured to clear the content. Care must be taken to prevent environmental contamination from the use of this material.

  • Ingestion: Do not induce vomiting. Treat symptomatically and get medical attention immediately.
  • Inhalation: Remove from exposure. If there is any difficulty in breathing, get medical attention immediately.
  • Skin Contact: Remove contaminated clothing. Immediately flush affected area thoroughly with mild soap and water.
  • Eye Contact: Immediately flood eyes with plenty of water for a minimum of 15 minutes holding the eyes open.
