​​MasterRoc MP 303CE - Low-viscosity, fast-reacting acrylic resin for permanent water sealing and layer curtaining of concrete and masonry

How does MasterRoc​​​ MP 303CE work?

MasterRoc MP 303CE is a highly reactive two-component acrylic sealing resin with a low viscosity for good penetration. The product cures quickly, forming a highly flexible hydrogel with extraordinary swelling/re-swelling properties. MasterRoc MP 303CE resin has been designed for usage as a permanent water sealing and layer curtaining resin. It is used for low pressure injection in concrete and masonry.

Recom​​​mended for use in:

• Stopping minor water infiltration
• Curtain injection
• Repair of cracks and fissures in concrete
• Permanent sealing of tunnel linings, shafts and masonry

What are t​​he unique features of MasterRoc MP 303CE?

• Very low viscosity
• Controlled gel time between 14 seconds and 3 minutes at 68 °F (20 °C)
• Workable between 41 °F (5 °C) to 104 °F (40 °C)
• Good bond strength to fractured rock and concrete, even under wet conditions
• Excellent swelling (up to 200% of initial volume) and re-swelling behavior (while maintaining self-healing properties)

What are the bene​​​fits of MasterRoc MP 303CE?

• Environmentally preferable – harmless in contact with ground water and no emission of potentially harmful substances
• Low viscosity allows deep penetration into very fine fissures and cracks
• The cured resin is resistant to acidic and alkaline solutions as well as many other solvents
