Cutback SC 70
SC-70 is a slow curing cutback made by blending bitumen with a low-volatility oil. The number gives its minimum kinematic viscosity at 60°C (70–140 mm²/s), so SC-70 is thin enough to penetrate and prime porous surfaces.
Where Cutback SC 70 is used
Cutback bitumen is bitumen blended with a petroleum solvent so it can be applied at low temperatures. Once laid, the solvent evaporates and leaves the binder behind. The solvent type sets the curing speed.
- 01Dust control, road-mix work and slow-setting maintenance mixes
- 02Priming of unbound granular bases before asphalt
- 03Cold-mix asphalt for maintenance and remote sites
- 04Projects without hot-mix plants or heating equipment

Storing Cutback SC 70
Temperature: Store and apply at the lowest temperature that gives a workable viscosity. Heating drives off solvent and raises fire risk.
Containers: Keep in closed, sealed tanks or drums to stop solvent evaporating, which changes the grade.
Fire safety: Cutbacks contain flammable solvent. Keep them away from open flames and sparks, earth the equipment, and keep fire extinguishers at hand.
Ventilation: Store in well-ventilated areas and avoid breathing vapours. Follow local rules on VOC emissions.
