VPU-1 Single Component Waterbrone Hydrophilic Polyurethane Grouting Materials for Waterproof Plugging and Reinforcement Repair of Cconcrete Leakage
Introduction
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.
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 concretion
body, 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.
