Introduction to Cutback Bitumen

Cutback Bitumen SC800, also known as cutback bitumen, is asphalt cement that has a solvent or distillate added to it, such as gasoline, diesel fuel, kerosene, or naphtha. This addition liquefies the asphalt at ambient temperatures, enhancing its ability to coat aggregates effectively. The designation of cutback asphalt typically consists of two letters followed by a numerical digit, indicating its specific grade or type.

Uses of Cutback Bitumen SC-800

Penetrating Prime Coats

One of the primary applications of SC-800 cutback bitumen is in penetrating prime coats. It is used to prepare surfaces before overlaying them with asphalt mixtures, enhancing adhesion and waterproofing capabilities.

Patching or Stockpile Mixtures

SC-800 is also commonly utilized in producing patching or stockpile mixtures. Its ability to lower viscosity makes it suitable for mixing with aggregates, ensuring proper coating and bonding of loose mineral particles.

Waterproofing and Surface Coating

Moreover, cutback bitumen SC-800 is ideal for waterproofing surfaces and plugging capillary voids. It provides a durable coating that helps in preventing water infiltration and protects the underlying structures.

Packing and Safety Measures

Packing Details

SC-800 cutback bitumen is available in bulk tanker shipments as well as new steel drums securely palletized to prevent leaks. Proper packing ensures the integrity of the product during transportation and storage.

Safety Precautions

It is crucial to adhere to safety guidelines when handling cutback bitumen SC-800. Always refer to Safety Data Sheets (SDS) before use, and follow these key precautions:

Transport, use, and store at the lowest feasible temperature.

Eliminate ignition sources during application.

Avoid inhalation and skin contact; wear appropriate personal protective equipment (PPE) and heat protection when necessary.

Prevent products or washings from entering stormwater or sewer systems.
