Gilsonite or Natural Bitumen is also known as Natural Ashphalt, Asphaltine, or Asphaltom and is soluble in petroleum asphalt solvents. Gilsonite is used in the hardening of oil products and it is easily converted to powder form.
Gilsonite, Natural Bitumen or Natural Asphalt is a Non-hazardous, naturally occurring hydrocarbon resin that is similar in appearance to coal or hard asphalt.
Iranian Gilsonite is the other brand for the mineral known as natural bitumen which is found in Kermanshah and Gilane Gharb located in Iran and also found in Utah in the United States, but can be obtained from Iran at a fraction of the price than that of the U.S.
Gilsonite primarily is used in dark-colored printing inks and paints, oil well drilling mud and cements, asphalt modifiers, foundry sands additives and a wide range of chemical products.
Gilsonite is used in news inks and heat set and gravure inks. Various concentrations of Gilsonite Resin are used to produce other special inks with a higher shine. Some of Gilsonite’s ingredients are found in black jet inks used by printers.
Gilsonite comes in Lump and Powder form and is usually sold in 25 Kg Bags.
The use of Gilsonite in Oil
Iranian Gilsonite is used in drilling mud fluids and oil well cementing. The addition of Specially-treated Gilsonite to water-based drilling fluids minimizes entire washouts by stabilizing shales, and properly seals highly permeable sands while reducing torque and drag. By adding Gilsonite to oil wells cement it reduces slurry weight without loss of Compressive strength and acts as an effective bridging and plugging agent to seal fractures in weak structures.
Gilsonite in Asphalt and Road Paving
Iranian Gilsonite is used as a performance-enhancing agent for asphalt mixes. By using Gilsonite one can virtually replace, or complement, the use of SBS polymers in modified asphalts and lower their cost. Gilsonite can improve performance under stress and can reduce deformation caused by reduced temperature susceptibility and increased resistance to water stripping.
Our Company proudly brings Gilsonite into our Factory before processing it for packaging in lump or in powder form whereas other suppliers in order to save on costs do the packaging on site at the mine where the pollution is at the highest. The benefit of our method is that there will be less ash and disturbances to its greater qualities and it can be tested reliably each time by our Quality Engeneers with extensive History in the Production of Bitumen products before being introduced to our clients. This extra care consists of an extra transportation cost to our Factory In Esfahan but it is well worth the benefits it
