Bitumen RC-70 (Rapid Curing Cutback Asphalt)
Bitumen RC-70 is a rapid-curing cutback bitumen widely used in road construction, prime coating, and surface dressing. Produced under ASTM standards, this grade ensures durability, adhesion, and optimal performance.
General Information of Cutback Bitumen RC-70
Cutback asphalt is produced by blending penetration-grade bitumen with solvents such as kerosene, gasoline, or naphtha. These solvents reduce viscosity, making RC-70 cutback suitable for spraying, mixing, and prime coat applications.
Uses of RC-70
- Prime Coat & Cold Application: Easy application without heating, saving time and energy in construction.
- Surface Preparation: Improves durability by binding loose particles and preparing non-asphalt surfaces.
- Waterproofing: Fills capillary voids and enhances long-term protection.
Packing Options for RC-70
RC-70 is supplied in new steel drums (200L), 25kg pails, bulk tankers, and bitutainers. All packaging is SGS approved and suitable for long-distance export.
Safety Guidelines
- Refer to Safety Data Sheet (SDS) before use.
- Store and transport at lowest safe temperature.
- Avoid inhalation of vapors and skin contact.
- Keep away from ignition sources.
Quality Guarantee
ensures RC-70 meets ASTM/EN standards. Shipments are inspected by third parties (SGS, BV, GeoChem) with full COA, MSDS, and QC test results before export.
