TamPur 150 MDI is a 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. TamPur 150 is a 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 approved Excellent adhesion to most surfaces including concrete, brick and mortar Resistant to most organic solvents, mild acids and alkalis Reacts even with seawater or mineral water Typical Applications TamPur 150 MDI 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 MDI will foam to expand and fill the void, forming a tight, impermeable elastomeric seal, stopping the water flow.
