668 Polyurethane Resin Foam Injection for Grouting Machine

Introduction

Hydrophobic Polyurethane Foaming Agent is a single component hydrophobic water cut-off grout and soil stabilization grout based on a MDI (Methylene Diphenyldiisocyanate) polyurethane. The cured material is semi flexible and of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not effected by water or dryness. The reacted material does not shrink or swell.

 

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.

Advantages   

• Once contact with water, react immediately and expand. It can also expand when contact with vapor in the air.
• High elasticity, hardness and low toughness.
• Exceptionally strong adhesion strength with the sustrate and good mechanical resistance(anti-water, seawater, waste water, dilute acid or alkaline chemicals)
• do not have air shrinkage phenomenon.
• It has nontoxicity after complete reaction.  

 

Application

• Defective Concrete(Cracked or honeycombed)
• Concrete Joints
• Undergrounds
• Brick Construction
• Roof and ground improvement
• Window frame, hair cracks
• Drinking Water Reservoirs
• Sewers, Manholes, Utility Boxes, etc.
• Tunnels, Dams
• Soil Stabilization

 

Packing and storage  

 

9-10kg per round iron pail. Store indoors with good ventilation and keep away from fire, sunlight. 

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.
