VPU-2 Hydrophobic Oil Grouting Materials for Waterproof Plugging and Reinforcement Repair of Concrete Leakag
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.
