Gilsonite in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder. This natural asphalt is similar to a hard petroleum asphalt and is often called a natural asphalt, asphaltite, uintaite, or asphaltum. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due to its unique compatibility, gilsonite is frequently used to harden softer petroleum products.

Gilsonite is brand name for the mineral known as asphaltum, uintaite, Natural asphalt, mineral tar, mineral pitch, mineral bitumen, bitumen powder, drilling, asfaltite, asphaltite which is found in commercial quantities only in west of Iran. Gilsonite is compatible with microcrystalline and paraffin wax, petroleum resin and oil, rosins, tall oil pitch, vegetable oil (linseed, soya, etc), petroleum process oils and petroleum asphalt.

As one of the main supplier of Gilsonite products, we market many different grades of Gilsonite and Gilsonite resins, each with properties tied to a specific end-use.

Gilsonite in Asphalt & Bitumen

Gilsonite Natural Asphalt , Natural Bitumen , Hard Asphalt or Hard Asphaltum is used as a performance-enhancing agent for asphalt mixes. Gilsonite-modified asphalts have higher stability, reduced deformation, reduced temperature susceptibility and increased resistance to water stripping than non-modified asphalts. Gilsonite is also used to make both solvent-based and emulsion pavement sealers with superior appearance and weathering properties.

Gilsonite in Oil & Gas

Gilsonite is used in drilling mud fluids and oil well cementing. The addition of Gilsonite to oil well cements reduces slurry weight without loss of compressive strength and acts as an effective bridging and plugging agent to seal fractures in weak formations while cementing.

Gilsonite in Inks and Paints

Gilsonite Resin is widely used as the primary carbon black wetting agent for black news inks and headset and gravure inks. Iranian Gilsonite Resin competes advantageously with petroleum-based hydrocarbon resins, phenolic resins and metal resinates, all of which it can complement or replace to various degrees. Various concentrations of Iranian Gilsonite Resin are used to manufacture law-rub-off news inks with superior gloss and tack properties. For Paint , If added to asphaltic paints and varnishes, Gilsonite’s unique qualities improve their roughness, gloss and chemical and weather resistance. For printing Inks, Gilsonite is an important cost-effective ingredient in the manufacture of high quality vehicles for dark printing inks.

Gilsonite in Foundry

Gilsonite is combined with coal and other ingredients as an additive in foundry sands to insure the quality of the molded part by improving mold release and the overall finish of metal castings.

Gilsonite in Chemical

Gilsonite has many industrial applications, including metal alloy processing, refractary, steel desulfurization, friction products, wood products, waterproof pipe coatings, and adhesives. Gilsonite is used as a binder and mixing agent in steel desulfurization products. It will also add carbon content to the steel and will provide a reductive atmosphere as it oxidizes at high temperatures. Gilsonite is used to make waterproof coatings for water pipes. The wood products industry also uses Gilsonite as a binder. It has excellent waterproofing and weather resistant properties. Because Gilsonite is a hard resin it will make a very hard particleboard.
