Concrete-foaming Agent Non Toxic Building Materials

It is a single component hydrophobic water cut-off grout and soil stabilization grout based on a MDI (methylene-dephenyl-isocyanate) polyurethane. Upon contact with water it reacts to a foam while expanding its volume up to 30 times. The cured material is semi flexible and of a constant volume. Since water is not a component of the foam structure, the cured material isessentially not effected by water or dryness. The reacted material does not shrink or swell.

Appearance: Light yellow to brown transparent liquid

Density: more than 1.00 g/cm3

Sticky degree less than 1000 mpa.s

The times of absorbing water more than 10-40

Foaming rate more than 350%

Time of solidification less than 150s

Advantages

1. It has low sticky degree, so doesn’t lead to blocking due to the improvement of sticky degree inside coating pipe. Also, it has easy construction & good operation.

2. It has good water-soluble, so don’t result in the residual water exited in cracks which will destroy the foaming for a long time, finally leading to secondary water leakage.

3. It finishes the solidification when going through water after 20-120 seconds.

4. It has good stability and don’t go bad during the construction after opening the seal. Also, it can keep in reserve, without deteriorating, for half a year before breaking the sea.

5. It has well sticky with concrete and good colloidality, no delaminating with concrete.

6. It doesn’t affect the physical property of the foaming when going through mete-acid, sea water and so on.

7. It has a long-time water resistance, strong structure & high toughness.

Matters needing attention

Wearing protective equipment (gloves, masks, goggles) to avoid skin contact directly when in perfusion, please rinse with water if contaminated with slurry, inadvertently contaminated on eyes should look for medical care immediately after water rinsing .
