VPU-1 Single Component Waterbrone Hydrophilic Polyurethane Grouting Materials
for Waterproof Plugging and Reinforcement Repair of Concrete Leakage
Introduction
VPU-1 is a common one-component hydrophilic polyurethane grouting material. The
composite
polyether polyol reacts
VPU-1 is a common one-component hydrophilic polyurethane grouting material. The composite polyether polyol reacts with the polyisocyanate to form a hydrophilic chemical grouting material terminated by isocyanate. It reacts rapidly with water, solidifies and expands the closed crack, thereby achieving Quickly stop the water. This product is milky white elastic colloid after reaction with water. It has the advantages of high speed, high strength, small shrinkage and strong impermeability. It is widely used in waterproof tunneling projects such as subway tunnels, water conservancy and hydropower, underground garages and sewers with the |
polyisocyanate to form a hydrophilic chemical grouting material terminated by isocyanate. It
reacts rapidly with water, solidifies and expands the closed crack, thereby achieving Quickly stop the
water.This product is milky white elastic colloid after reaction with water. It has the advantages of high
speed, high strength, small shrinkage and strong impermeability. It is widely used in waterproof tunneling
projects such as subway tunnels, water conservancy and hydropower, underground garages and sewers.
Characteristics
1.Low viscosity, quick reaction in water, forming impervious
elastic colloidal concretion body by
reaction with good water sealing performance.
2.Reacting with water, it forms ivory elastic colloidal
concretionbody, which has the advantages of
high compressive strength,low temperature resistance,good
elasticity and penetration proof quality.
3.Good effect on mixing with water. The product can penetrate into
crack deeply and the crack can
be sealed thoroughly by concretion body.
4.Good dilatability,big water content ,good water affinity and
groutability, meanwhile the viscosity
and curing speed can be adjusted according to customer's
requirement.
5.It can be widely used in waterproof projects such as DAMS,
subway, tunnel etc.

The Difference Between VPU-1 And VPU-2
| Item | VPU-2 | VPU-1 |
| Characteristic | Hydrophobic PU Grouting Materials;High Foaming Rate,Good Stability.And Fast Speed | Hydrophilic PU Grouting Materials;High Solid Content,High Water Content,Low Shrinkage,Fast Speed |
| Reaction Time | 15-20 Minutes | 10-20 Seconds |
| Waterproof Features | Not Reacting with Water,Foaming, Displacing Water | Reacts With Water to Form a Solid State |
Shortcoming | The reaction speed is slower than VPU-2 and the price is relatively higher | Long Time,Easy Evaporation of Moisture,and Easy Shrinkage of the Tire Body |
| Advantage | No Shrinkage,Good Stability | Fast Response Speed and Relatively Low Price |
| Construction Environment | No shrinkage,Good stability | There are no restrictions on the environment,whether it's dry,wet,or open water |
Proposal | Experienced craftsmen offline generally use water-based and oil-based construction methods,regardless of the environment,whether it is dry or wet,with or without visible water,because its cost is relatively low,more stable | |
