Rock Bolting
What is unique about MasterRoc® RBA 380?
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.
