BASF presents new fire-resistant grease for underground construction





BASF SE presents the fire-resistant grease MasterRoc TSG 800 for tunnel boring machines. It is the latest innovation of the Master Builders Solutions product range.
The lower density product enables customers to reduce consumption. In addition, improved packaging allows for easier recycling.
MasterRoc SLF 50, a new generation soil conditioning agent, has been specially designed to improve performance through the control of the soil during tunnelling operations under challenging soil conditions. This soil conditioner creates a highly stable foam with superior half-life to maintain face pressure during operation and planned or unplanned stoppages. It can lessen power consumption through torque reduction, optimize soil extraction and can decrease wear to the cutter head. MasterRoc SLF 50 was used successfully in one of the world’s largest diameter tunnels being built in Seattle.
