VPU-1 Polyurethane Waterbrone Hydrophilic Grout Materials
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.
