Retardant bitumens with the abbreviation MC are obtained by combining pure bitumen with a semi-heavy industrial solvent such as kerosene. This bitumen is black in color and has a higher viscosity than quick-acting bitumen. Retardant bitumen can be used at lower temperatures, which saves fuel. After 24 hours of using this bitumen, the solvent in it evaporates and pure bitumen remains. The quality of retarding bitumen depends on the quality of its solvent, and this also affects the viscosity of the bitumen.
Medium Curing Soluble Bitumen or MC is a type of bitumen that uses semi-heavy solvents such as kerosene in their production, and its solvent evaporates more slowly compared to gasoline and naphtha.
Types of bitumen retarder solution
Retardant bitumens are divided into five categories based on their viscosity using the centistokes (Cst) standard. These bitumens can be sold in bulk or in tankers, IBC tanks and 220 liter barrels
MC-30
It has the lowest viscosity among retarding bitumens. This bitumen has 58% pure bitumen in its composition and is the most widely used retarding bitumen in the market.
MC-70
64% of pure petroleum is used in the production of this retarder bitumen. MC-70 retardant bitumen is more viscous than the first type and is black in color.
MC-250
It has 84% pure bitumen and has a higher viscosity than the first two types. The solvent in this type of bitumen starts to evaporate in a longer period of time.
MC-800
Retardant black soluble bitumen has 80% pure bitumen and is more viscous. This bitumen is in the fourth category of retarding bitumen.
MC-3000
MC-3000 soluble retarding bitumen has the highest viscosity among the remaining retarding bitumens. This bitumen is produced from 85% pure bitumen.
Technical specifications of bitumen retarder solution
Bitumen has high adhesive properties, water resistance. These characteristics make bitumen an ideal material for use in construction and road construction projects.
