Cutback Bitumen Mc 70


Cutback Bitumen Medium Curing MC-70, offered by Global Synergy Company, represents a remarkable innovation in the construction and infrastructure sector. Its medium curing speed, versatility, and balanced properties make it a valuable asset in road construction, surface treatment, dust control, and waterproofing. As Global Synergy Company continues to provide top-notch MC-70 products, the global construction industry can leverage this exceptional material to achieve sustainable and resilient results in various projects.

Cutback bitumen is a mixture of bitumen and a solvent, typically derived from petroleum distillation. The "Medium Curing MC-70" designation refers to its medium curing speed, which makes it suitable for a range of applications. It possesses a unique ability to adjust its consistency during application, offering a balance between penetration and viscosity.

Applications and Advantages
  • Pavement Construction: MC-70 is a favored choice for road construction due to its optimal curing rate. Its medium viscosity allows it to penetrate gaps and adhere effectively to aggregate materials. This results in durable and high-strength road surfaces that can withstand heavy traffic loads and varying weather conditions.
  • Surface Treatment: The versatility of MC-70 extends to surface treatment applications. It can be used for prime coats, tack coats, and fog seals. Its moderate curing rate ensures proper adhesion between existing and overlaying layers, enhancing the overall structural integrity of the pavement.
  • Dust Control: In unpaved areas such as construction sites or mining operations, MC-70 proves its worth by controlling dust. Its medium curing properties allow it to bind loose soil particles, minimizing fugitive dust emissions and creating a safer and cleaner environment.
  • Waterproofing: MC-70 is also employed in waterproofing applications, effectively sealing surfaces against water infiltration. Its balanced consistency ensures that it can be applied evenly, forming a protective barrier that prevents moisture from compromising structural integrity.
