cutback bitumen MC-70

General information of cutback bitumen MC-70

Cutback Bitumen MC-70 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function. Cutback MC-70 use in Roofing – As a waterproofing membrane and as an adhesive to stick chippings onto a flat, horizontal roof to minimize the effects of weathering from the sun.

Cutback bitumen MC-70 is dissolved of bitumen in solvents of kerosene. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen. The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long-term softening effect may result.

Our MC-70 Cutback Bitumen complies with cutback petroleum asphalts of the Medium-Curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004. Cutback Grade Bitumen is normally used in spraying and in some mixing applications. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline, and naphtha, controlling the curing time. Cut back petroleum asphalts of the rapid curing type supplied by BITUMENSHOP Co are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by BITUMENSHOP Co is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. The cutback bitumen (Asphalts) supplied by BITUMENSHOP are blended from petroleum grade bitumen as stated herein.

Uses of cutback bitumen MC-70

Cutback agents are used to lower the viscosity of bitumen when it is applied as a primer to the surface of a road pavement aggregate base course or substrate. Kerosene is used as a bitumen cutback agent at different concentrations according to local conditions and requirements.

The cutback bitumen is ideal for prime coat and cold applied because of easy uses and no need to thinning and heating.

Cutback bitumen MC-70 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.

The cutback asphalt MC-70 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.

Current common uses are in penetrating prime coats and in producing patching or stockpile mixtures. Cutback asphalt used in mixing with aggregate will usually contain an adhesion agent to assist in the coating of the aggregate surface.

Packing of cutback bitumen MC-70

This cutback bitumen bulk in the tanker and also in new steel and thick drum on the pallet to prevent all leak inside of the container.

Safety of cutback bitumen MC-70

Refer to Safety Data sheets before use.
Transport, use and store at the lowest temperature possible.
Eliminate all potential ignition sources during application.
Avoid breathing vapors. Avoid contact with skin.
Always wear appropriate PPE including heat protection when used hot.
DO NOT allow product or washings to enter stormwater or sewer systems.

cutback bitumen RC-3000

General information of cutback bitumen RC-3000

Cutback asphalt is an asphalt cement that has a solvent or distillate such as gasoline, diesel fuel, kerosene, or naphtha added to make the asphalt liquid at ambient temperatures and improve its ability to coat aggregates. Two letters followed by a numerical digit designate or name a cutback asphalt.
Cutback asphalt can contain between 12 and 40 percent distillate. The high demand for the distillates to be used in energy applications and ever-increasing air quality regulations have caused a steady decline in the use of cutback asphalt.
When gasoline or naphtha is used to flux asphalt cement, the final product is called “rapid curing” (RC) cutback asphalt. Specifications permit up to 45 percent distillate in manufacturing an RC-3000 cutback asphalt.

Our Cutback Bitumen RC-3000 complies with cutback petroleum asphalts of the rapid-curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004.
