Gilsonite (Natural Asphalt) Price History
Brief Description About Gilsonite (Natural Asphalt)
Gilsonite (Natural Asphalt) is a naturally occurring solid hydrocarbon resin, also known as uintaite. It is mined primarily from natural deposits and appears as a brittle, black, glossy material.
Gilsonite is widely used as an additive and modifier in various industries due to its high carbon content and strong binding properties. Its main applications include:
- Asphalt and road construction (to improve strength, durability, and resistance)
- Oil & gas drilling fluids (as a shale stabilizer and fluid loss control agent)
- Foundry and casting, inks, paints, and industrial coatings
