669 polyurethane material for injection machine
Product introduction
This product is a low-solvent structure flexibility colloidal single liquid (water) 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 feature
1. Good chemical resistant performance
2. Ultra-structure of elastic foam colloidal reinforcement
3. Good flexibility
4. Strong adhesion with the substrate
5. For single-fluid high-pressure grouting machine
Application
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.
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.
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.
