MC-70 Bitumen: Medium-Curing Cutback Bitumen for Prime Coat and Penetration Applications
MC-70 Bitumen is a type of medium-curing cutback bitumen consisting of penetration grade asphalt cement blended with a petroleum solvent such as kerosene. This solvent temporarily reduces the viscosity of the bitumen, making it easier to handle and apply. After application, the solvent evaporates, leaving the bitumen to perform its primary function.iranrequest., utilizing advanced refining technology, produces and supplies this product with quality conforming to ASTM D2028-97 standard.
Manufacturing Excellence and Innovation
iranrequest. MC-70 Bitumen is produced through precise blending of penetration grade bitumen with kerosene in controlled proportions. The production process is carried out under strict temperature control and using advanced equipment, resulting in a uniform product with consistent properties. This type of bitumen, due to its unique characteristics, provides an ideal solution for specific applications in the road construction and waterproofing industries.
Key Features and Benefits
- Optimal Viscosity: With a kinematic viscosity of 70 to 140 mm²/s at 60°C, it provides easy application capability.
- Medium Curing Rate: Provides sufficient time for penetration into the surface while setting at an appropriate speed.
- Excellent Penetration: Penetrates well into pores and cracks of surfaces, increasing the adhesion of subsequent layers.
- Water Resistance: After drying, creates a waterproof layer on the surface.
- Ease of Use: Does not require excessive heating and can be used at ambient temperature or with minimal heating.
- Standards Compliance: Fully compliant with ASTM D2028-97 (reapproved 2004), ensuring global quality assurance.
Primary Applications
MC-70 Bitumen, due to its unique characteristics, has diverse applications in the industry:
- Prime Coat: An ideal material for use as a primer on granular and aggregate surfaces before asphalt overlay.
- Surface Penetration: Filling capillary voids, coating, and bonding loose mineral particles on road surfaces.
- Roofing Waterproofing: Used as a waterproofing membrane and as an adhesive to stick chippings onto flat, horizontal roofs to minimize the effects of weathering from the sun.
- Patching Mixtures: Production of cold asphalt mixtures for road repair and maintenance.
- Dust Control: Used for stabilizing earth surfaces and reducing dust on unpaved roads.
- Cold Applications: Ideal for use in conditions where heating bitumen is not possible.
