JBY668 polyurethane foam grouting materials for concrete crack waterproofing

Product Introduction

 

This product is a low-solvent structure fixing single liquid (oil) polyurethane injection grout, with water, the rapid expansion of the solidified plug the cracks reach the sealing; can also be used in conjunction with the low amount of catalyst, according to the actual construction needs to adjust the quick response, its the perfect waterproof stanch effect.

Product Description

 

 

1. The low viscosity in contact with water from a chemical reaction immediately and foam expansion.

 

2. Ultra structural reinforcement, high expansion ratio, toughness good, not contraction.

 

3. And substrate adhesion and chemical resistance (resistance to drinking water, sea water, wastewater dilution of the acid-base chemical supplies)

 

4. Contact with the drinking water of the region can also be used. 

 

5. Used with single liquid high pressure grouting machine and other equipment.

 

 

 

Application Places 

 

1. Filling the tunnels, dams, basement, brick wood, dry, wet concrete member crack, actual bond all contact surfaces.

 

2. Crack injection of pressurized water groundwater flow, with the use of catalysts to the formation of foam in three seconds, 10 minutes after contact with water can be completely foam expansion and solidification.

 

 

 

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 and physical property.

 

 

 

 

 

 

Attention

 

 

Wear protective equipment (gloves, masks, goggles) to avoid skin perfusion when in direct contact, please rinse with water if contaminated with slurry, the eyes to inadvertently This product should be with plenty of water and seek medical care immediately.
