Cutback Bitumen Supplier
Tiger Bitumen Company has the capability to Supply the different Grades of Cutback Bitumen in compliance with National and International standards. Cutback Bitumen is a range of binders that are produced by blending (mixing) penetration grade Bitumen and a hydrocarbon solvent, such as paraffin or mineral turpentine. Three types of solvents are used for the blending process: Slow-Curing, Medium-Curing or Rapid-Curing solvents. The latter two are the most common in South Africa. The choice of the solvent determines the rate at which the Bitumen will cure when exposed to air. A Rapid Curing (RC) solvent will evaporate faster than a Medium Curing (MC) solvent. Curing relates to the evaporation rate of the solvent which influences the setting time of the Bitumen. The viscosity of the cutback Bitumen is determined by the proportion of solvent added. The higher the proportion of solvent, the lower the viscosity of the cutback.
