​​MasterRoc SLF 670​​

MasterRoc SLF 670 is a concentrated, biodegradable, high-performance and highly stable foaming agent, specifically designed to improve the performance and control of the soil through the screw conveyor under the toughest conditions. MasterRoc SLF 670 foaming agent is ideal for heterogeneous grounds with variable ranges of permeability. ​​

What are the unique features of MasterRoc SLF 670?

• Remains stable in temperatures as low as 23 °F (-5 °C)
• High foaming capacity
• Generates fine, uniform, and stable foams
• Creates plastic deformation properties in the soil
• Lowers inner friction and abrasiveness of the soil
• Helps obtain desired soil rheology with decreased foam injection ratio (FIR) values

What are the benefits of MasterRoc SLF 670?

• Suitable for a wide range of tunneling environments
• Improves face support pressure control and increases face stabilities
• Improves soil behavior and reduces soil permeability
• Improves TBM excavation cycle time and quality
• Reduces risk of surface settlement
• Reduces soil blockage and promotes easier mucking
• Reduces cutterhead and screw conveyor wear
• Reduces foam consumption
• Reduces logistic complexities​
