Product Description

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

Scope of Apllication
1.Deformation Joints in Construction Projects Deformation Cracks,Construction Joints, Structural Joints,

   Plugging and Reinforcement of Structural Cracks
2.Undergound Tunnel
   Subway Tunnels,Subway Platforms,Highway Tunnels,Railway Subgrade Tunnel Walls
3 Ports and Wharves
   Bridge Piers,Dams,Hydropower Station Curtain Grouting Plugging and Reinforcement
4 Leakage Plugging by Retaining Walls in Geological Driling Selective Water Plugging

in Oil Exploration and Water Gushing in Mines,etc.
