Medium-curing

Medium-curing cutback bitumen

Cutback binder specified by curing type and viscosity.

Overview

MC-30 · MC-70 · MC-250 · MC-800 · MC-3000

Medium-curing cutback uses a solvent system that evaporates more slowly than rapid-curing cutback. The grade number identifies its viscosity range at 60°C. Selection for prime coats, cold mixes or maintenance follows the project specification and local restrictions.
