MC70 Bitumen – Medium Curing Cutback Bitumen for Prime Coat and Cold Mix
MC70 Bitumen is a medium-curing cutback bitumen formulated for prime coating, patching, and cold mix asphalt production. It consists of penetration-grade bitumen blended with a medium-volatility solvent like kerosene, which allows for easy spraying and deep penetration into aggregate layers. As a reliable Iranian MC70 bitumen supplier, we deliver high-purity MC70 from Iran and Iraq for road projects across Asia, Africa, and the CIS region.
Product Description
MC70 is known for its moderate viscosity and medium evaporation rate. It provides superior adhesion between the granular base and asphalt layer, making it an essential material in flexible pavement construction. This grade is especially useful in regions with warm climates where rapid curing is required, but where MC30 would evaporate too quickly.
