Two Component High Pressure Injection Polyurethane
Emecole Metro 100/800 Polyurethane & Catalyst expands up to 25 to 30 times its initial volume, making it an ideal high pressure injection material for the repair of leaking joints or cracks in concrete. As a hydrophobic polyurethane, Emecole Metro 100/800 maintains its physical closed cell form and is not subject to shrinkage.
The system is comprised of a base resin along with an accelerator “B” component which must be mixed prior to injecting. Since Emecole Metro 100/800 Polyurethane & Catalyst will not react until it comes in contact with moisture, the mixture can be prepared days before use, if stored in a completely dry environment.
High Pressure Injection Polyurethane with Catalyst
The reaction profile is adjusted prior to pumping by the addition of catalyst into the base resin and is affected by temperatures and the amount of moisture encounter. At 1.25% (1/2 pint per five gallons) the expansion will start in about 35 seconds and be complete in about 3.5 minutes after encountering water. At 2.5% (1 pint per five gallons) the expansion will start at about 25 seconds and be complete at about 2 minutes. These reaction times were determined at 77ºF with the addition of 2.5% water.
