Product Description:
Dr. Fixit PU Foam Injection is based on MDI (Methylene Diphenyl is a cyanate) polyurethane pre-polymer & accelerator. The system only reacts when it comes in contact with water, producing a relatively stiff & inert polyurethane foam. It is a 100% solid & solvent-free polyurethane grout for quick temporary closing & sealing of water-bearing cracks, cavities, and leaks under hydrostatic pressure. The system foams to 30-40 times its volume in the presence of water & can be an effective means of arresting running water seepage because it provides deep penetration, shrink free solid mass, strong bonding inside the cracks and excellent resistance to honey combing & chemicals.
Features and benefits
- Consistency – Very low viscosity and highly penetration in fine cracks and cavities.
- Durability – Provides structural strength and rigidity.
- Compatibility – It is not compatible with water hence injection grouting is possible in presence of water in the substrate.
- Curing – It cures in presence of water like dampness, leakages, moist surface.
- Bonding – Bonds strongly to brick, stone & cementitious substrate in air & to wet surfaces.
- Non-toxic – It is approved by CFTRI for drinking water contact
