Conditions underground vary from mine to mine and rock temperatures can range from -5 °C up to 60 °C. This variance can influence the curing speed of reactive resins. Another consideration is that different pumping lengths require different set times.

MasterRoc RBA 380 is a fast-reacting, two-component polyurea silicate injection resin offering many advantages over cement and cartridge systems.

• Unique thixotropic behavior for use in overhead applications without additional sealing
• Fills even the smallest cracks (≥ 0.14 mm)
• Long-distance pumping capability up to 30 meters
• Fast curing and strength development
• Does not run or sag
• Can be used in rock bolting at all angles
• Higher mine efficiency
• Increased miner safety during bolting operations
