Polyurethane injection is a high-tech insulation method used for waterproofing structures. In this method, special two- or one-component liquids (polyurethane resins) are injected into cracks or gaps in the structure under high pressure. When these liquids come into contact with water, they rapidly foam and expand, filling the cracks completely and preventing the passage of water. This waterproofing application is an effective method preferred for the permanent solution of water-related problems in many areas such as reinforced concrete structures, tunnels, dams and parking lots. It also stands out with its solvent-free, high adhesion strength and long-lasting properties.
DF PUR INJEKTION 2K Polyurethane Injection Resin
It is a two-component, solvent-free, polyurethane injection resin that reacts in contact with water.
Advantages
- Reduced water requirement for curing and reaction
- Adheres to wet and dry surfaces
- Remains active when water is low
- Resistant to water or chemical solutions
- Non-toxic, no harm to the environment
- Not biodegradable by micro-organisms
Application Areas
- Sealing of gaps, fine cracks and joints
- Sewers and manholes
- Subsoil shear walls subject to high water pressure
- Treatment plants
- Elimination of water leaks in foundations
- Sealing of expansion joints.
Application Features
The reaction time is controlled by using between 2% and 10% of the accelerator known as Catalyst 10. The expansion time depends strictly on the amount of accelerator mixed with the resin, the amount of water and the application temperature. After the reaction of the product with water, a flexible, hydrophobic, non-shrinkable foam is obtained. The product does not expand without water but hardens, forming an elastic mass.
Warnings and Recommendations
Flammable, combustible and flammable products should be kept away during application. Smoking should be avoided. Care should be taken to ensure continuous ventilation of the application area. Protective equipment such as goggles and gloves should be used during application. In case of eye contact, wash thoroughly with plenty of water. Request Material Safety Data Sheet for detailed information. Keep out of the reach of children. The product should be consumed by professional users, taking into account the data in the technical information section.
