VPU-2 PU Oil Hydrophobic Grouting Materials

VPU-2

Hydrophobic PU Grouting Materials

Introduction

VPU-2 is a common one-component hydrophilic polyurethane grouting material. The

composite poly 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.
