Hydrophobic Single Component Polyurethane Grout OPU-25

SE OPU-25 is a hydrophobic single component MDI based polyurethane grout. When it comes in contact with water, the resin will react rapidly to produce a highly expanded and semi-flexible polyurethane foam.

Product description

BENEFITS

  • Rapid expansion of foam to stop water leakage
  • Excellent for sealing high pressure water infiltration
  • Ease of use, only single component
  • Non-toxic and environmentally friendly
  • Does not shrink
  • Resistance to chemical attack or corrosion
  • Excellent bonding and semi-flexible
  • Low viscosity
