Introduction
VPU-2 is one component hydrophobic PU grouting material, it
reacts with water and expand to be a foam does not dissolve in the water.
Not only used for waterproof plugging, but also with effect of reinforcement. It is widely used in subway tunnels, water conservancy and hydroelectric power, basement parking, sewage etc for waterproof plugging and reinforcement projects.
Characteristics
1.With good hydrophobic properties, high chemistry stability.
2.With larger Penetration radius and solidification volume ratio,
react with water quickly with large expansion pressure, pushing
the liquid to the depths of crack and expand to form a tenacity
consolidation.
3.Resistance of acid, alkali and organic solvent, better resistance of
chemical corrosion;
4.Coating smooth, wear-resisting, no mildew ;
5.Excellent adhesiveness with concrete base and other construction
materials;
6,Viscosity and cure speed can be changed according to the
requirement of projects.
