Single component hydrophilic polyurethane in combination with polyether polyols. It only reacts when it comes in contact with water and forms a flexible polyurethane seal.
This product can be enhanced with the addition of a polymer based reinforcing agent, to give enhanced resilience.
Key Benefits
- Potable water certified
-
High tensile adhesion
-
Solvent-free, environmentally safe.
-
Excellent adhesion to most surfaces including concrete, brick and mortar.
-
Resistant to most organic solvents, mild acids and alkalis.
-
Rapidly forms a highly resilient flexible seal that allows movement to the crack, fracture or joint.
- Reacts even with seawater or mineral water
Typical Applications
TamPur 150 is a hydrophilic polyurethane prepolymer liquid for hydrophilic polymer resin type water stopping.
It can be injected directly into a leaking crack, fracture or joint, or it can be injected 1:1 with water.
After injection has taken place, the TamPur 150 will foam to expand and fill the void, forming a tight, impermeable elastomeric seal, stopping the water flow.
