Slow Curing

SC70, SC250, SC800, SC3000

Slow Curing (SC) asphalt cement and oils of low volatility generally in the heavy distillate range (SC-30, SC-70, SC-250, SC-800 and SC-3000). The degree of liquidity developed in each case depends principally on the proportion of solvent to asphalt cement. To a minor degree, the liquidity of the Cutback may be affected by the hardness of the base asphalt from which the Cutback is made. The degree of fluidity results in several Grades of Cutback asphalt—some quite fluid at ordinary temperatures and others somewhat more viscous. The more viscous grades may require a small amount of heating to make them fluid enough for construction operations.



Cutback SC800

Cutback bitumen SC800 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 founders in the year 2012 have established the Kiapetro company with the aim of better providing and making use of Bitumen and Petroleum Products.
