MC 70

MC-70 is a cutback bitumen which is a penetration bitumen asphalt blended with kerosene. Kerosene and other petroleum derived products are added as cutback agents reducing the viscosity. Mc-70 means solvent is medium caring which express that the solvent will vapor at medium speed. During applying the MC-70 cutback bitumen, the solvent evaporates so the residue demonstrate perfect adhesion. The bituminous cutback asphalt MC-70 is recommended to use for road construction.

 

The main applications of MC-70 cutback are prime sealing, prime coating , manufacturing of asphalt pre-mix and  maintenance of the road. Due to their lower viscosity medium caring cutback bituminous asphalt is proper for cold weather condition. medium curing cutback petroleum asphalt supplied by bitumen supply manufacturing from vacuum distillation of crude oil blended with a petroleum solvent.

 

INTERNATIONAL BITUMEN SUPPLY guarantee to supply  the cut back asphalt MC-70   in compliance to the mentioned specification in table.

 

Packing: Bitumen supply is able to provide every packaging according to customers enquiry.
