What is Gilsonite? Uses, Properties & Industrial Applications
Gilsonite is a naturally occurring, solid bitumen (also called asphaltite or uintaite or Natural asphalt) found in vertical veins beneath the earth’s surface. It is a black, brittle, resin-like substance with a shiny luster and is highly compatible with petroleum-based systems. Because of its excellent binding, waterproofing, and thermal stability, Gilsonite is widely used across construction, oil & gas, chemical, adhesive, and ink industries.
It is a unique, shiny black substance that is found in select regions around the world, with the largest deposit located in the Uinta Basin in Utah, USA, although similar materials are found in other parts of the world, including Iran, Colombia, and Turkey.

Major Industrial Uses of Gilsonite
Additive
One of the primary uses of Natural bitumen is as an additive in different industries, including foundry and casting, printing inks, paints and coatings, adhesives and sealants, and more. Its versatile properties make it a valuable ingredient for enhancing performance, durability, and quality in various applications.
In the foundry and casting industry:
Gilsonite is used in molding sands:
-
Improves mold release
-
Enhances surface finish
-
Reduces casting defects
Natural bitumen acts as a binder, improving the strength and durability of molds. It can withstand high temperatures and reduces casting defects such as veining and scabbing, resulting in smoother cast surfaces and improved metal quality.
In the printing inks industry:
In black ink and industrial coatings:
-
Provides gloss and color depth
-
Reduces drying time
-
Adds chemical resistance
Gilsonite functions as a natural thickener and rheology modifier, improving ink viscosity and flow properties. It also enhances pigment dispersion, intensifies color, and contributes to better print adhesion and stability.
In paints and coatings:
Gilsonite acts as a binder and reinforcement agent, enhancing durability, resistance to weathering, and adhesion to various surfaces. It also enhances color intensity and glossiness, providing a high-quality finish.
In the adhesives and sealants industry:
Gilsonite improves:
-
Tackiness and flexibility
-
Water and chemical resistance
-
Bond strength and durability
Natural bitumen improves bonding strength, resistance to temperature fluctuations, and protection against moisture and chemicals. It also helps control viscosity and provides stability to formulations.
Chemical Manufacturing
Used as a binder, carbon filler, or base resin in:
-
Friction products (brake pads)
-
Carbon-rich formulations
-
Resin and plastic manufacturing
When using Gilsonite in any application, it is crucial to consider the specific formulation, desired performance objectives, and compatibility with other components. Manufacturers should follow guidelines and consult experts to determine the appropriate dosage and blending process.
