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.

Recommended 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 the 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 benefits of MasterRoc MP 303CE?

  • Environmentally preferableharmless 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
