Medium Curing

MC30, MC70, MC250, MC800, MC3000

Cutback MC30

Cutback bitumen MC30 is dissolved of bitumen in solvents of kerosene. MC-30 grade has the highest demand. MC-30 is a medium curing cutback bitumen that contains 55% bitumen and has the lowest viscosity among all grades.


Application of Bitumen Cutback MC30

Cutback Bitumen MC30 are used as components for road maintenance industry where it is used as a prime coat of the base course prior to placing of the bituminous surface course.

The cutback bitumen is ideal for prime coat and cold applied because of easy uses and no need to thinning and heating.

Cutback Bitumen MC30 is used Priming of all non-bituminous road buses, provision of temporary surfaces(deviations)

Also, Cutback Asphalt MC-30 is suitable for primer sealing and can also be used in the manufacturing of asphalt pre-mix.
