Key Specifications/Special Features:

  • Product introduction:
    • LW hydrophobic polyurethane chemical grouting is a kind of one component and excluding water material, which is formed via polyisocyanates and polyether polyol reacted under certain conditions
    • When grouting, NCO perssad meets water, the reaction of chain extension, branching, cross-linking and solidification are produced, therefore, stop water rapidly and reinforce concrete effectively
    • Meanwhile heavy expansion pressure is generated so that make the grouting diffused again
    • Accordingly, push the grouting forward to permeate crack and hole deeply
    • So it has enough scope of diffusion and solidification
  • Characteristic:
    • Rapid solidification: reaction, foaming, solidification are generated after meeting water, adding the catalyst to adjust the time of reaction, the solidification time is usually controlled within 10 seconds
    • High strength: under hermetic condition, the compressive strength can be 17 to 20MPa in 4 hours, 25 to 30MPa compressive strength and 3MPa bonding strength can be reached in 24 hours
    • Big expansion ratio: since foaming, the expansion ratio can be 20 times
    • The grouting is single component with convenient operation
    • Steady chemical construction of induration: good property of bearing chemical resistance and bio-erosion
    • No chloridion, no corrosion to steel
  • Applications: mainly applied to treatment of basic seepage-proofing in concrete expansion joint, crack, construction joint of water conservation water and electricity, tunnel, subway, civil defense, metallurgical engineering, industrial and civil architecture
  • Storage period:
    • Shelf lifespan: 6 months in original package, dry place, 5 to 30°C
  • Package: 20kg or 25kg in a iron drum
