MasterRoc MP 358 SC - Highly reactive, two component hydrophobic polyurethane injection resin for strata consolidation 

How does MasterRoc MP 358 SC work?

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. 

Where is MasterRoc MP 358 SC applied?

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

What are the advantages of MasterRoc MP 358SC?

  • 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 0.14mm. 
  • When in contact with water, the foam factor may increase to about 8.
  • Low sensitivity to water.
  • Almost no increase of reaction temperature in contact with water. 
  • Good bonding on wet and damp surfaces
