Description
Cutback bitumen MC-70
Cutback bitumen MC 70 producing way would be the same as other MC bitumen and it will make from high-quality Bitumen dissolved in kerosene solvents in Asia Bitumen solvent towers. the solvent of MC 70 would be kerosene and for a better quality of final product, the quality and solvent both of them must be with high quality and without any impurity.
Cutback Bitumen MC-70 uses
MC 70 or medium cure cutback bitumen is used for reducing or diluent the viscosity of Bitumen in road construction normally is spraying cutback asphalt MC 70 on the surface of the road Asphalt and its very good for first coating because it doesn’t need to make it heat.
cutback asphalt MC 70 is used for waterproofing surface cracks like cracks on the Asphalt in roads and in roofs of constructions it can use for waterproofing the surfaces of non Asphalt constructions.
the main uses of cutback asphalt MC 70 are used in the surface of places for increasing adhesion of surfaces before asphalting them or waterproofing these surfaces with Asphalt.
Cutback Bitumen MC-70 Packing
Packing of Cutback Asphalt would be normally bulk in tankers or with new steel or recondition thick drums with pallets.
Cutback Bitumen MC-70 Maintenance conditions
Cutback Asphalt MC 70 must handle and store in low-temperature conditions because its vapor would be flammable.
