MC30 Cutback Bitumen – Medium Curing Bitumen for Prime Coating

MC30 Bitumen is a medium-curing cutback bitumen, primarily used for prime coats in road construction before laying asphalt layers. It is a mixture of penetration grade bitumen and medium-volatility solvents like kerosene. MC30 is a low-viscosity liquid that penetrates granular surfaces, creating a strong bond and waterproofing the base. As a trusted Iranian MC30 Bitumen supplier, we provide high-quality material from Iran and Iraq, compliant with international standards.

Product Description

Bitumen MC30 is designed for low-temperature application and rapid penetration into road bases. It is commonly applied as a prime coat on uncoated aggregates before placing the first asphalt layer. MC30 is especially effective in dusty or dry conditions and ensures proper adhesion between layers. Its medium curing rate balances workability with drying time, making it ideal for both rural and highway projects.
