Product Details
Summary
LD 333 is a kind of one-component polymer water plugging material formed by chemical reaction of isocyanate and polyether.
Features
● Excellent hydrophobic properties, high chemical stability;
● One component grouting, low viscosity, good irrigability
● The viscosity and curing speed of the grouting liquid can be adjusted according to needs;
● Excellent penetration radius and solidification volume ratio, and emits CO2 in chemical reaction when it meets water. The pressure generated by the gas drives the slurry to diffuse to the depth of the crack, forming tough consolidated body;
● Acid, alkali and organic solvent resistance, good chemical resistance;
● Smooth surface, wear-resistant, no mildew;
● Excellent bonding performance with concrete base and other building materials;Technical Data
| Items | Parameter |
| Aspect | Pale yellow or brown translucent liquid |
| viscosity | 200-1000 Mpa.s |
| Density | 1.10-1.20 g/cm3 |
| Coagulation time | 200s-800s |
| Contraction percentage | No shrinkage |
| Expansion rate | ＞2500 % |
The viscosity and density are tested at 20°C.
Application
● To prevent slow leakage and intermittent leakage from crack area;
● Sealing for leakage of various buildings, tunnels, expansion joints, construction joints and other structures;
● Suitable for plugging in places with small water output;
● Apply to crack plugging of bridge piers, dams, hydro-power stations;
● Ground stabilization of tall building / railway / express way, as well as crack plugging and settlement prevention of water reservoir.
