Formerly MEYCO MP 358 SC

What is MasterRoc MP 358 SC?

MasterRoc MP 358 SC is a two component, solvent-free polyurethane injection resin specifically designed for rapid stabilization of strata where high compressive and bonding strength is needed.

Fields of application

  • Consolidation of fractured rock in underground structures
  • Consolidation of broken coal in development roadways and longwalls
  • Sealing against gas and water

Features and benefits

  • Fast reacting material applied where structural strength and flexibility is required.
  • Reacts and expands in volume up to 3 times without water contact.
  • Penetrates cracks wider than 0.14 mm.
  • When in contact with water, the foam factor may increase to about 8.
  • Low sensitivity to water.
  • Almost no increase of reaction temperature on contact with water.
