Cutback SC 70 for dust control and road-mix work. Exported from Dubai.
A slow-curing cutback bitumen with a low viscosity, so it sprays and penetrates easily. Applied without heating.
Slow-curing binder for long working time
Cutback SC 70 is a slow-curing cutback bitumen: penetration-grade bitumen thinned with low-volatility oil so it can be applied without heating. The grade name gives the minimum kinematic viscosity at 60°C (70 mm²/s).
The oil used to cut the bitumen is low in volatility, so it leaves the binder very slowly. This gives long mixing and laying time and suits dust control, road-mix work and stockpiled mixes.
Black Rock Bitumen supplies Cutback SC 70 from Dubai to contractors, EPC companies and road maintenance agencies across Asia, Africa and the Middle East.
